perl-after-upgrade mistakenly thinks nothing needs to be done

[Mike Brown]

Hi all,

I'm running 8.3-RELEASE and thought I'd update Perl from 5.12 to 5.16.
Silly me. I updated my ports snapshot, and as per UPDATING, ran

	portmaster -o lang/perl5.16 lang/perl5.12

This went OK, so I then ran perl-after-upgrade, with and without -f. It scans 
the packages and finds everything it should, but insists nothing needs to be 
done, saying " 0 moved, 0 modified, 0 adjusted" for every one of them. At the 
end it says "Fixed 0 packages (0 files moved, 0 files modified)".

Well of course this isn't right; all my modules are still sitting in the
5.12.4 directory and are not getting moved over to the 5.16.2 one. This 
naturally breaks everything depending on those modules.

What's going wrong? Sorry if this is a novice question.

Please let me know what I need to check. Thanks,

Mike
