Update to 5.8.6. Also:
- redirect output from h2ph to /dev/null [1];
- fix File::Path insecure file/directory permissions [2];
this resolves CAN-2004-0452
(http://vuxml.freebsd.org/c418d472-6bd1-11d9-93ca-000a95bc6fae.html);
- for OSVERSION < 500036, create symlinks in /usr/bin not only for
perl and suidperl, but also for a2p, c2ph, find2perl, h2ph, h2xs,
perlbug, perlcc, perldoc, pl2pm, pod2html, pod2latex, pod2man,
pod2text, s2p, and splain; perl and suidperl are still enough for
more recent FreeBSD versions [3];
- clean up created symlinks upon deinstallation [4];
- try to cleanup symlinks created by older versions of lang/perl5 and
lang/perl5.8, during both installation and deinstallation [5];
- added support for DISABLE_BSDPAN environment variable [6];
