Hey folks,
Maybe there is a Perl/CPAN list that is a better place to ask this?
If so, maybe someone can point me to it.
Anyway, I want to be able to script the installation of a bunch of
CPAN modules, and the first basic problem I am coming up against is
that the "cpan" command seems to always return 0 regardless of whether
or not the install completed.
Google does not bring up a whole lot of help for me here, but I have
to think this problem has already been solved.
Thanks for any guidance you can give.
-Alan

You installing these locally in a non root users home? :) If not, I can tell you that will wreak havoc if a Perl related updated comes down the pipe via yum...

Check the epel and rpmforge repositories. This will make things go much smoother both now and when you need to update later. -- Bowie

Have you checked epel/rpmforge/etc. for the modules you need? -- Les Mikesell lesmikesell at gmail.com

Hi, i don't know exactly if this would be usable for yourself, but very nice feature for our purposes is autobundling, see for example: http://search.cpan.org/~andk/CPAN-1.9402/lib/CPAN.pm#POPULATE_AN_INSTALLATION_WITH_LOTS_OF_MODULES or http://www.developertutorials.com/tutorials/cgi-perl/automate-perl-module-deployment-050426/page4.html As for RPMs, it could be sometimes problem with versions. RPMs aren't often the most recent versions of modules and resolving RPM dependencies could sometimes overwrite the most uptodate versions (which you need) by slightly older which may not be applicable. But this really depends...

The CPANPLUS module has been included with Perl for several years and I recommend investigating its cpanp command-line program instead of cpan. And if you want something even more up to date, you can look at cpanminus - which is packaged as perl-App-cpanminus at my CPAN/RPM repository (http://rpm.mag-sol.com/). Finally, can I repeat the advice that other people have hinted at. Mixing CPAN-installed modules and RPM-installed modules in a single Centos installation is a really bad idea. I highly recommend using only RPM-packaged modules (and learning to build your own[1] for ones that you can't find elsewhere). Cheers, Dave...
