Just before old package deinstall, scan the list of files installed by
old port (pkg_info -g). Match .so.X files under PREFIX/lib and any
ldconfig'ed paths 1*), copy them away to /usr/local/lib/compat/pkg.

After installation of new port, match .so.X files again. If same
filenames appear, remove old copies from /usr/local/lib/compat/pkg.

Finally, ldconfig -r /usr/local/lib/compat/pkg


1*) portupgrade currently gets this wrong and saves all .so* files,
including uninteresting things like plugins etc.
