I always find this a good opportunity to upgrade Perl. Given the fact
that upgrading perl and all the ports that depend upon is a pain,
having to rebuild all the ports is always a good excuse to do it.

For the amount of ports installed on a production server combined with
todays horsepower, a full rebuild doesn't take more than a couple of
hours. On a desktop it is a bit more complicated but it is always a
good opportunity to toss some ports that are useless.
