CentOS - Jun 2018 - installing perl-CPAN without perl-local-lib

I'm still working on getting my brand new Centos 7 mail server working and
I'm
having problems with Perl.

Most of the modules are available as RPM's which was straight forward. 
However, MIME::Parser, Net::SCP and Net::SSH aren't.

In order to get these working I installed the perl-CPAN rpm and then installed 
the modules above.  Doing this, installed perl-local-lib.noarch as a 
dependancy. 

The problem now is that when I used CPAN to the above modules they installed 
without errors, but were only available to the root user.

I can't uninstall perl-local-lib without uninstalling perl-CPAN and I
can't
install perl-CPAN without installing perl-local-lib.

Any ideas on how I can get to do the simple task of installing these modules 
system wide?

There's lots of info on it on the web. For the definitive answers look
long the local::lib pages on CPAN - basically there are environment
variables you can set to say where things are to be installed.

Also, I think when you first run CPAN one of the questions it asks is
where to install things - if you let CPAN configure itself it defaults
to a local install. You can re-run the CPAN initial config by doing 

  o conf init

at the CPAN prompt.  You may have to clean up your .bashrc as well.

This is probably the most useful link I found

You might want to build rpms for these perl modules, not so hard with 
cpanspec, eg:

I simply removed the bashrc entries and that was enough to let me install the 
modules system wide.  I will also investigate cpanspec when I get more chance
