It works OK 99% of the time for me, but as I told Pierre, I usually build Python into the gtk prefix. It 
seems to work better than relying on Apple's Python for

It should be in $PREFIX/share/gir-1.0/.

Well, it *should* be optional, but configure.ac wants introspection.m4, which is provided by 
gobject-introspection. 
If you don't actually need introspection for something (gtkmm and pygobject are the most popular, but there 
are plenty of other uses), you could work around it by copying introspection.m4 to $PREFIX/share/aclocal/ and 
skipping the build of GI.

What have you got going in /usr/local/include? You're not using that as your prefix, are you?
