Very strange. I tried to reproduce this on 64-bit Ubuntu 12.04 (by
removing my ATLAS, BLAS, LAPACK etc..) but couldn't:

$ python -c "import numpy; numpy.test()"
Running unit tests for numpy
NumPy version 1.6.2
NumPy is installed in
/home/scott/.virtualenvs/numpy-tmp/local/lib/python2.7/site-packages/numpy
Python version 2.7.3 (default, Aug  1 2012, 05:14:39) [GCC 4.6.3]
nose version 1.2.1
.........

Ran 3568 tests in 14.170s

OK (KNOWNFAIL=5, SKIP=5)
