can't find libperl.so after security update

[Volker Jahns]

There is some problem after upgrading perl because of security issues:
exim, imapd won't run w/o libperl.so

Probably there is more of this sort, but that is what I immediately figured on my production machine.

Manually adding a missing link to /usr/local/lib/libperl.so works. 

What is the recommended procedure to follow for perl upgrade on FreeBSD 5.3 release?
