in getting mirror-2.3 to work with FreeBSD, i found that timelocal.pl has
a bug. a patch is included below. this needs to be applied to both
src/gnu/usr.bin/perl/lib/timelocal.pl and
src/usr.sbin/xntpd/scripts/monitoring/timelocal.pl
Submitted by: jmb
and /usr/share/perl (library). The latter was chosen as analogous to other
directories already present in /usr/share, like /usr/share/groff_font and
(particularly) /usr/share/mk.
