Like this?

Is it perfectly safe if I simply add
    perl5.branches 5.8 5.10 5.12 5.14 5.16 5.18 5.20
to the PortGroup and then start removing "perl5.branches" from
individual perl ports? If so, I would add that line, but I need a
confirmation from more experienced users.

I have mixed feelings about that. If nothing else people might install
modules with CPAN, then update MacPorts and their scripts might stop
working.

We certainly need to fix a lot of things related to Perl, but it's
basically impossible to figure out which modules could be removed. We
might end up removing one module just to discover that someone
submitted a ticket to request some other piece of software that
requires the deleted module.
