The best way would probably be to use libmachista during the install
phase to determine what the mach-o files in each port are linked with,
and record that in the archive metadata and the registry.

Then, much like the problem of finding out which (uninstalled) port
provides a file you want, it's just a matter of setting up a way to
query that information.

Or if you want a way that doesn't involve writing any code, figure out
the linking situation manually and put a comment in the portfile.
