multiple versions of pcre needed with pkgs and ports

[Mark Felder]

Never mix packages and ports. You would have to be using the EXACT  
snapshot of ports that the package team used to build the packages for  
this to be safe. So conclusion: use one or the other, but never both.

Things you need to be doing now:

1. Install sysutils/bsdadminscripts and run pkg_libchk
2. Recompile every package it lists with broken libraries
3. Continue using ports from now on

Everyone learns this the hard way, so don't worry :-)
