perl-5.8.9 breaks MRTG

FreeBSD 7.0-Release
MRTG-2.16.2,1 stops working after perl-5.8.9 update 1-14-2009

cd /usr/ports/textproc/p5-Pod-Parser
make deinstall
make reinstall

cd /usr/ports/net-mgmt/p5-SNMP_Session
make deinstall
make reinstall

cd /usr/ports/net-mgmt/mrtg
make deinstall
make reinstall

That fixed it for me. I'm sure there's a more elegant/efficient way to do this, but I figured I'd give everyone notice.
AFFECTS: users of lang/perl5.8

lang/perl5.8 has been updated to 5.8.9. You should update everything
depending on perl. The easiest way to do that is to use
perl-after-upgrade script supplied with lang/perl5.8. Please see
its manual page for details.

That probably would have done the same thing? Maybe? *shrug*...
The perl-after-upgrade script is often neglected. It is very easy and quite useful. That should've fixed the problem and I only post a reply to confirm this solution to anyone upgrading perl and breaking perl dependencies thereafter.
portupgrade -f "p5*" fixed my issues with ports failing after upgrading perl.

The perl-after-upgrade script did not.
Yeah, the perl-after-upgrade script did absolutely nothing to resolve my problems with mrtg and its dependencies on 4 different Freebsd 7.0/7.1 servers. Had to manually deinstall/reinstall the listed ports to get mrtg working.
