I suspect this is the problem: numpy-1.4.0 is considered broken and has
been withdrawn. Specifically, it introduces binary incompatibility with
programs compiled against prior versions of numpy, including matplotlib.
If you go back to the numpy sourceforge site now, I think you will see
an earlier version that you can install in place of 1.4.0 (after
removing the latter).
