This may very well come back to bite you in the future, causing 
mysterious failures long after you've forgotten you did it.  Here's a 
little Ruby script to detect these (it needs updating to work with pkg):

Running pkg_libchk [-q] after port upgrades has worked well for me.  It 
is from sysutils/bsdadminscripts by Dominic Fandrey, and easily detects 
applications that are using old libraries and should be rebuilt.  It 
worked this time also.
