Well, the version of numpy that is actually installed does appear to
be 1.0.4, not 1.2.1. It is possible that you have old files left over
from a previous installation or you have two numpy packages installed
to different locations, and the old one is the one that is getting
picked up.

Do the following to double-check the location of the installed numpy:

>>> import numpy
>>> print numpy.__file__

You may need to delete this installation of numpy thoroughly and reinstall.
