It is already unsupported for users to have anything in /usr/local  
while using MacPorts. We don't want to now reverse that policy.

bin: and lib: dependency styles wouldn't search /usr/local. Well, I  
suppose, unless the user added /usr/local/bin to binpath in  
macports.conf. But that would be unsupportable.
