Looks like a binary format issue to me. What does 


file /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/numpy/core/multiarray.so

give you, and how does it compare to 

file /Library/Frameworks/Python.framework/Versions/2.6/bin/python

Maybe you need to strip the binaries to your native arch, using lipo.
