Py-numpy on Darwin

[Jason Bacon <outpaddling%yahoo.com@localhost>]

Py-numpy was failing with “cannot find a valid fortran version”.  I fixed that with the following addition:

Now it’s failing with a faulty library path.  Before I deep dive into the bumpy build system, thought I’d ask if anyone has seen this issue before and knows how to fix it.

Thanks,
