Are you sure that this is the same numpy as the one being picked up
during the scipy build? Since you are executing the scipy build as
root, you may be getting different numpy packages. In order to see the
path of the numpy package, do this:
In : import numpy
In : numpy
Out: <module 'numpy' from '/Users/rkern/svn/numpy/numpy/__init__.pyc'>
"I have come to believe that the whole world is an enigma, a harmless
enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
