The Perl provided by your OS is ancient (yes, it is) and probably broken. We can fix that. Most of your programming problems are probably solved by a Perl module from CPAN, but if you don't know what that is, or how to install modules from it, you'll never use it. We can fix that as well. You've got production code that needs to keep running, but you still want to forge on with modern tools and approaches. We can help with that as well.
This talk provides a rapid introduction to perlbrew, cpanminus, and local::lib.
