Let's look at what didn't work.

Yep. This is safe to ignore. What RPM is saying here is that the user
who originally built this package ("mockbuild") isn't on your
system.
"mockbuild" is the unprivileged user/group that the Fedora buildsystem
uses to build packages. However, part of that warning is something you
should not ignore:

" - using root".

You should not be building software as root. That path leads to terrible
pain and destruction. When you're ready to install the software you've
built, su to root, but not before.

These messages come from RPM and they say "I've checked my database of
packages against what this src RPM says it needs to build and nothing
provides these". RPM isn't psychic. It only knows about packages that
have been installed by RPM. Anything you build from source by hand is
not known to it at all. These "perl(Foo::Bar)" dependencies are
provided
by perl packages, where Foo::Bar is the CPAN module. You can see an
example of this by querying the perl package:

[spot at localhost ~]$ rpm -q perl --provides
perl = 4:5.22.1-355.fc24
perl(AnyDBM_File) = 1.01
perl(AutoLoader) = 5.74
perl(AutoSplit) = 1.06
...

This allows you to say:

yum install "perl(AnyDBM_File)"

And yum will go find the RPM package that Provides: perl(AnyDBM_File)
and install it for you. You don't have to remember the name of the
package, just the CPAN module name.

Points to you. perl-libintl Provides: perl(Locale::Messages). That
package actually exists in Fedora 17, so you can do:

   sudo yum install "perl(Locale::Messages)"

And it will install it for you. The same is true for
"perl(Text::Unidecode)" but sadly, not for
"perl(Unicode::EastAsianWidth)".

That built the src rpm into binary packages for Fedora 17.

That's fine. For future knowledge, you only need to install the
debuginfo packages if you're planning on running the binaries in the
main RPM through gdb. Otherwise, it's just eating space on your hard drive.

Here's where you got off the main road:

Installing modules via CPAN is the same as building them by hand: RPM
doesn't know they exist.

And that's where you lost hope. What you need to do is to keep tracing
down RPM packages for dependencies and rebuilding. Normally, most Fedora
users don't have to do this, because we build a whole repository of
packages for them, but since you're 6 (almost 7) releases out of date,
you've got harder work to do.

koji.fedoraproject.org is your friend here. You can search for srpms
there, download them, and rebuild them.

That said, since you've listened to all of this, I've installed a Fedora
17 VM instance on my laptop and built you the missing packages you need
to build R fully featured:

https://spot.fedorapeople.org/fedora17-R-deps/

There is a src.rpm in there too for texlive, you don't need to install
it, I just included it because I had to make a minor fix in that package
to reflect the dependencies available in Fedora 17 (but really only to
install the texinfo-tex subpackage, which I don't think you need to
build R... but still, better complete than not).

Good luck!

Well, if you ever make it to New Zealand, get in touch and I will shout 
you dinner and all the wine you can drink at a restaurant of your 
choice.  The effort you've put into this is way above and beyond the 
call of duty.

Ah, errmmm, I'm at a loss.  I *didn't* su to root at all.  Ever.  The
warning said "using root" --- but I didn't, in any way, tell the 
rpmbuild command to do it's work as root.

What am I not understanding here?

This is kind of irrelevant anyhow since you've built for me all the 
stuff that I need.

So let's cut to the chase:

Thank you for going to all this work.

However (as usual) I'm still at a bit of a loss.  I *think* that just a 
few more words of instruction will get me to where I need to be.

I went to the site that you specify and there found a list of 14 
packages (rpm-s) one of which is a ".src.rpm" with the others end just
in ".rpm" with no ".src" before it.

OK.  Now what do I do?

Do I download each of these and install them, in the order that they are 
listed?  Or is there some other incantation that should be invoked?

I tried downloading the first rpm listed, id est

     info-6.0-2.fc17.1.x86_64.rpm

and then did

     rpm -i info-6.0-2.fc17.1.x86_64.rpm

but this gave me an error:
> error: can't create transaction lock on /var/lib/rpm/.rpm.lock
(Permission denied)
So I then tried:

     sudo rpm -i info-6.0-2.fc17.1.x86_64.rpm

and got *some* action, but also got a plethora of messages:
> file /sbin/install-info from install of info-6.0-2.fc17.1.x86_64 conflicts

They don't say "error" but I am not sure what the implications
are, so I
stopped at that point in case I screw things up even further than I 
already have.

I didn't see anything that I could identify as a src.rpm for texlive. 
The one src.rpm that I see is

     texinfo-6.0-2.fc17.1.src.rpm

Is this what you mean?

Thanks again.  Hoping for further enlightenment.

cheers,

Rolf

Download all of them, except for the src.rpm (and the texinfo-debuginfo
package).

Then, run:

sudo rpm -Uvh info-6.0-2.fc17.1.x86_64.rpm
perl-File-ShareDir-Install-0.10-3.fc17.noarch.rpm
perl-Module-Install-AuthorRequires-0.02-10.fc17.noarch.rpm
perl-Module-Install-AuthorTests-0.002-10.fc17.noarch.rpm
perl-Module-Install-ManifestSkip-0.24-4.fc17.noarch.rpm
perl-Module-Install-Repository-0.06-10.fc17.noarch.rpm
perl-Module-Manifest-Skip-0.23-4.fc17.noarch.rpm
perl-Module-Package-0.30-9.fc17.noarch.rpm
perl-Module-Package-Au-2-4.fc17.noarch.rpm
perl-Unicode-EastAsianWidth-1.33-6.fc17.noarch.rpm
texinfo-6.0-2.fc17.1.x86_64.rpm texinfo-tex-6.0-2.fc17.1.x86_64.rpm

rpm has two install modes:

 * -i installs new packages.
 * -U upgrades a package over an existing install

The reasons for these modes are historical trivia, practically, humans
always use -U, because -i chokes if a package is already present, which
is what you saw. -v tells rpm to be verbose, and -h tells it to do
pretty progress hashing.

hth,

~tom

PS. I totally meant "texinfo" when I referred to the src.rpm earlier.
Too much tex on the brain today.
