I'm far from an OS X installer expert, but after some puttering and
trial and error I came up with a patch that seems to work.  I created
http://hackage.haskell.org/trac/ghc/ticket/4354 and attached the
patch.

The main question is whether or not I can kill Uninstaller, as it's
even more broken now than it was before.  If yes, I'll attach another
patch that removes it.

Oh, and I think I may have accidentally sent the patch to
cvs at ghc.haskell.org thanks to darcs' auto send thing, ignore that
please.
