I can check my Tiger machine in a few hours to see what would happen if you blacklisted gcc-4.0. I bet you'll have to blacklist gcc-3.3 too; that's the other gcc version Tiger has. But I have a feeling it won't automatically realize that using apple-gcc42 instead would be a good idea.

How about something like the following:

   reinplace "s|@@PYTHON_BRANCH@@|${prefix}|" ${worksrcpath}/setupext.py

 }

I don't a machine running Tiger (or Leopard, or even Snow Leopard) so
can't test this... Any other suggestions are welcome.

Cheers
