PierreForget,

I see you're using the system perl /usr/bin/perl. I suggest you at least consider not touching the system perl at all, instead building your own perl (as non-root) that you can safely control, and experiment with, and install CPAN modules to, without risking breaking your Unix system.

Conversely, Re: Prefer Pure Perl Core Modules notes that relying on the system perl couples you tightly to the OS' upgrade schedule, for both the language and CPAN modules ... so a "harmless" OS upgrade can potentially break your serious mission-critical systems, if they are using the system perl.

Many more references on this topic can be found at Re: Replicate Perl setup (Building and Installing Perl References).

If you're not doing serious stuff in Perl, you can just Forget about this advice. :-)
