[SciPy-dev] SciPy SVN compilation on SnowLeopard

I'm banging my head on some configuration issues for Scipy on Mac OS  
10.6. I followed the recommendations from this site [http://blog.hyperjeff.net/?p=160 
], but there's obviously something very wrong in my system: _csr,  
spline, numpyio cannot be loaded because of a wrong architecture.
(for example, the SciPy test suite gives me ImportError: dlopen(/Users/ 
pierregm/Computing/workspace/scipy-dev/scipy/io/numpyio.so, 2): no  
suitable image found.  Did find:  /Users/pierregm/Computing/workspace/ 
scipy-dev/scipy/io/numpyio.so: mach-o, but wrong architecture)

Any hint would be welcome.

And as a side note, I have to confirm bug #1194 of numpy (I have to  
symlink libnpymath.a to somewhere it could be found).

Here are some relevant details
