You read the FAQ at http://www.freebsd.org/gnome, and do the update
correctly.  It does work.  Your problem is you tried to upgrade gdm2 on
a system were all the other ports were not up-to-date already.  Bad idea
(for just about anything).  Instead, you should have used portupgrade
-ra to do things properly, and in the correct order.  Had you done that,
all your Perl dependencies would have been recorded correctly.
