Upgrading glib2 to universal fails (poorly) on zlib

[marco@…]

I was upgrading my glib2 port to a universal variant, and ran into a problem with zlib. To resolve this issue I had to upgrade my zlib port to universal as well.

Other ports warn nicely about having to upgrade to the universal variant. It would be pleasant if this one would as well, as my fix was just a wild guess at the problem.

Error: Unable to upgrade port: 1

This fixes it:
