Looks like there is a bug in the new API version tracking:

>>> import numpy as np
RuntimeError: module compiled against version 1000009 of C-API but this
version of numpy is 100000a
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/numpy/__init__.py", line 132, in

    from lib import add_newdoc

    from type_check import *
