Comment (by jmroot):

 Presumably you have something installed with variants that are not (or are
 no longer) default, leading to the different dependencies. That part isn't
 really a bug.

 The install failure does seem to be a bug. There have been other reports
 and we never worked out why it happened. It always seems to work fine
 after cleaning the affected port. If you had deleted
 `/opt/local/var/macports/build/_Users_glen_local_macports-
 ports_lang_perl5/perl5.24/work/destroot` without cleaning the port
 completely (i.e. the statefile still existed saying that the destroot
 phase was complete), that would explain it, but I guess you probably
 didn't.
