-arch i686 command line arg triggers build failure on mac osx 10.5.6 intel

[goatbar]

I'm trying to package scipy 0.7.0 for fink. It compiles fine on PPC, but I get this on my intel mac... I can't figure out where the arch is getting set.

Using built-in specs.

gfortran is coming from gcc 4.3.3

gfortran -dumpversion
GNU Fortran (GCC) 4.3.3

Update: scipy 0.7.0 compiles with numpy 1.1.1, but this error pops up when I switch to numpy 1.3.0 (Called scipy-core-py in fink)

[goatbar]

Also works with numpy-1.2.[01], so this is something that changed between numpy 1.2.1 and 1.3.0.

Whoops... that would be a numpy problem:

This is indeed a numpy bug
