Thanks, that helps. We do install some old libraries, but they'll be
going away soon.

However I have the same question about libraries. What are we going for?

 a) Any version of the library compiled against GTK 2.0 can be installed
    in parallel with the one built for GTK 3.0.

 b) The same version of the library compiled against GTK 2.0 can be
    installed in parallel with the one built for GTK 3.0.

This is relevant to gettext domains, UI builder files, and all the other
things I mentioned earlier.

Cheers,

Stef
