Trouble with Matplotlib 0.87.1 on Windows

I have problems getting matplotlib to work on Windows (ActivePython
2.4.2). After installing the precompiled binary packages for NumPy 0.9.5
and Matplotlib 0.87.1, I get this error message:

import pylab as p

Traceback (most recent call last):
  File "<pyshell#4>", line 1, in ?
    import pylab as p

line 25, in ?
    inf = infty = infinity = Infinity = (array([1])/0.0)[0]
TypeError: unsupported operand type(s) for /: 'numpy.ndarray' and 'float'

Is there an easy fix for this?
