That's a new one on me. Have you tried the latest release of numpy?

  http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103

If that still doesn't work for you, then please come to the numpy-discussion
list so we can figure out why it won't build for you. We will need to know
things like your platform, your compiler, and the actual text of the errors that
you are seeing.

  http://lists.sourceforge.net/lists/listinfo/numpy-discussion

But once you have it installed:

In [29]: A
Out[29]:
array([[0, 1],
       [2, 3]])

In [30]: numpy.linalg.det(A)
Out[30]: -2.0
