Actually compat port messes things a bit if a newly compiled binary is 
looking for new lib and it's next not-so-fresh dependency looks for the 
older one you'll get one set of symbols imported twice. libmap.conf is a 
  just a more painless solution, yet you should rebuild all binaries.

There's a good port sysutils/libchk which you can use to deal with this. 
It rummages through your bin/lib directories and reports any 
discrepancies it finds. It outputs something like:

Unresolvable link(s) found in: /usr/local/bin/lp
         libssl.so.5
         libcrypto.so.5
         libcrypt.so.4

I use this to create the list of packages I need to rebuild:

pkg_which `grep Unresolvable libchk.out | sed 's|.* in: ||'` | sort -u | 
grep -v '^\?$'

This list can be later given to something like portupgrade.

The same file can be used to automatically generate libmap.conf. However 
I havn't look at it.
