Finding / reinstalling modules

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I've recently upgraded perl from 5.12 (installed from RPM) to 5.14.1 (installed through CPAN).

Since the change, /usr/lib/perl5 and its subdirectories are no longer in my @INC, so half my scripts die because they can't find certain modules ... but if I try to install those modules, CPAN says they're still there.

So, what's the simplest (safe) way to either

Find out where CPAN thinks all my modules are and copy them over
Make CPAN reinstall latest versions of all the modules it thinks I've already got

Sounds like you're using the cpan script that was part of your 5.12 installation and not the one that's part of your 5.14.1 installation. -derby	[reply]

I've recently upgraded perl from 5.12 (installed from RPM) to 5.14.1 (installed through CPAN). As root? You should never upgrade the system perl but if I try to install those modules, CPAN says they're still there. Well, cpan is probably hardcoded (shebang) to use the 5.12 version of perl, for which, they are installed perlbrew is what you should study	[reply]
