[SciPy-user] 64 bit on Mac?

[Gins]

Thanks.  I successfully got python 2.6.2 compiled with 64 bit support,
but when I try to compile numpy I run into errors that are a little
beyond my experience:

gcc: build/src.macosx-10.5-universal-2.6/numpy/core/src/_sortmodule.c

and I haven't had any luck with the numpy .dmg files for mac.

I'll check out sage next and report back.  Thanks for the tips!
