Hi David,
This sort of error generally is due to having multiple copies of numpy
on your system. One is being used during compilation, and another
incompatible one is being used by your python interpreter.
I would do
apt-get uninstall python-numpy python-scipy
and then install numpy and scipy through easy_install. Hopefully that
will lead to only one numpy on your system. Otherwise, search for
multiple numpy versions and manually delete all but the one you want to use
