105osxpython:numpy Friedrich$ head
/Library/Frameworks/Python.framework/Versions/2.7/bin/nosetests
#!/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python

Same applies to the 2.6 & 2.5 :file:`nosetests`.  At least for the
2.7, the MacOS/Python called has different size than the bin/python2.7
cmd line executable.  So it's simply something completely different.
Still it makes the errors not explained.

I remember Ralf's post cited by himself.

FYI, the MacOS/Python executable has all three archs.

We came to the conclusion, so simple not use nosetests, and to leave
this mysterious issue to later, I will document it on the numpy build
doc web site.
