in reply to Anyone here using Linux Mint?

An alternative approach would be to install whatever Linux distribution you're happy with then install whatever Perl version you want. Using perlbrew it's trivial to install multiple versions of perl, while leaving the system perl alone (you can make life really difficult by messing with the vendor perl).

If you are testing your code against multiple versions of perl perlbrew can help here also by running it against all installed (via perlbrew) versions of perl:

perlbrew exec yourapp.pl
