What concerns should I have when installing additional Perl modules on a server?

Question

I would like to ask my system administrator to install various Perl modules such as `Moose` and `Data::Alias`. The system is Red Hat Enterprise Linux 5, running Perl 5.8.8. The only problem that I can think of is that some already-installed modules might need to be upgraded and thus run the risk of breaking something. What else should I be concerned about?

Accepted Answer

I do not know your company's policy, but it would probably be a better idea not to mess with your system `perl` and install the additional libraries and their prerequisites (and even a dedicated `perl`) in a different location and use `lib`.
