I'd go the other way around personally - anything that is critical to
development means not relying on some distro maintainers to keep up to
date - for serious systems it's better to use your own perl and CPAN.

cpan and cpanplus are both package managers, they just do Perl rather
than everything :)

Also freebsd package management plays nice with CPAN - it's debian and
redhat that are breaking things.

Of course you can just use PAR. In fact using PAR and bundling it in
with Bugzilla would make deployment a lot easier and simpler for new
