I just installed SciPy 0.9.0 with NumPy v 1.6.1 and Python 2.7.2.  Running scipy.test() reports one failure:

======================================================================
FAIL: test_expon (test_morestats.TestAnderson)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/software/python/2.7.2/lib/python2.7/site-packages/scipy/stats/tests/test_morestats.py", line 72, in test_expon
    assert_array_less(crit[:-1], A)
  File "/software/python/2.7.2/lib/python2.7/site-packages/numpy/testing/utils.py", line 869, in assert_array_less

  File "/software/python/2.7.2/lib/python2.7/site-packages/numpy/testing/utils.py", line 588, in chk_same_position
    raise AssertionError(msg)
AssertionError:
Arrays are not less-ordered

x and y inf location mismatch:
x: array([ 0.911,  1.065,  1.325,  1.587])
y: array(inf)

What do I need to do to fix this failure?

Other useful info:
Uname  -a:
Linux 2.6.18-194.11.4.el5 #1 SMP Tue Sep 21 05:04:09 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

Built using GCC 4.1.2, ATLAS 3.9.51, and Lapack 3.3.1.

The system has a working installation of SciPy 0.7.1 with NumPy 1.3.0, Python 2.6.4, ATLAS 3.8.3, and Lapack 3.2.1.
