Hi there,

I'm having a lot of trouble on Snow Leopard.

I'm trying to build a 32bit only version of our system....

Turns out I had to use python 2.7a3 in order to get Python --universalsdk to work....

But now numpy fails to build as well...

First because of the:
>>      _old_init_posix = distutils.sysconfig._init_posix
error

I got it to use sysconfig instead

But now when running python setup.py build install

I get:

Note: it's saying soemtihng about mac 10.3....

Any idea on how to build a pure 32bit numpy on snow leopard?

Thx,

C.
