[SciPy-User] build scipy on os x 10.6, python.org 2.7

[Robin]

Hi,

I am trying to build scipy (current trunk) on OS X 10.6 with
python.org 2.7 (32 bit).

There seems to be a problem that it is trying to build -arch ppc64 (log below).

Is there a way to disable this architecture (and even x86_64) so the
build will complete?
