>Description:
The Perl adds OPTIONAL_MANPATH to /etc/manpath.config.
/etc/periodic/weekly/320.whatis makes whatis database files under manpath of the Perl.
It interferes with the deletion of the directory.

Perhaps, lang/perl5.18, lang/perl5.14 and lang/perl5.12 have same problem.
>How-To-Repeat:
portmaster lang/perl5.12
periodic weekly # or wait Saturday's 4:15am
portmaster -o lang/perl5.16 lang/perl5.12
find /usr/local/lib/perl5/ -name whatis

This is a example of result:
% find /usr/local/lib/perl5/ -name 'whatis'
/usr/local/lib/perl5/5.12.4/perl/man/whatis
/usr/local/lib/perl5/5.12.4/man/whatis
/usr/local/lib/perl5/5.16/perl/man/whatis
/usr/local/lib/perl5/5.16/man/whatis
>Fix:
fix pkg-plist or do_cleanup_manpath() in files/use.perl.
remove whatis database file in there.
