Switching to Perl 5.20 as the default Perl version

[Mojca Miklavec]

Hi,

I believe that we are ready to make the transition to 5.20 as the
default version of Perl in MacPorts.

There is a small number of ports that still lack support for 5.20. But
that's about 1-2% of all ports only, and many of them are lacking
support just because they are broken under 5.16 anyway, or because it
would be nice to update the version first and that introduces extra
dependencies and extra work etc. We can always just add 5.18/5.20 to
the list of subports even for those semi-broken ports.

See http://trac.macports.org/ticket/46005 for details.

This is how we made the recent transition of switching ports from 5.12 to 5.16:
    http://trac.macports.org/ticket/44405
which took about 5 months for all the maintainers (not) to respond.

Thanks to a patch by Bradley (pixilla) it also became easy to add
perl5_xy variants to ports in order to support multiple Perl versions,
see details in the following ticket for example:
    http://trac.macports.org/ticket/46570

Does anyone volunteer to start the transition to 5.20 and open a
ticket similar to #44405 to switch from 5.16 to 5.20?
