This is a common issue on OSX.  If you enable PKG_DEVELOPER=yes then
the shlib checks will ensure that you find out at build time that
there is a problem rather than at runtime.

The fixes can be relatively straight-forward, and there are lots of
examples of how to do it in pkgsrc now, just look for install_name.
