You _rule_.  Thanks for the toe-hold.

Here is a patch against 2007Q4 that no doubt will break other things,
but seems to be working for me in light testing (at least it lets
devel/py-gobject-shared build cleanly):

I don't do bulk builds, so I can't do a proper survey to figure out
what this breaks, if anything.  Right now I'm trying to build
x11/py-gtk2, which had numerous issues previously, so that might be a
more extensive test.

Anyway thanks for the help everyone!
