Here's what I see on an up to date squeeze box:
% python
Python 2.5.4 (r254:67916, Feb 17 2009, 20:16:45)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> m = numpy.random.random((16, 16))
>>> (x, v) = numpy.linalg.eig(m)
>>> print numpy, numpy.__version__
<module 'numpy' from '/usr/lib/python2.5/site-packages/numpy/__init__.pyc'>
1.2.1
>>>
looks quite normal to me.
