[Numpy-discussion] test failure

After spending a lot of time building 'numpy' (1.5.0) and 'scipy'  (0.8.0) I
ran the following tests -- per what I read somewhere:
numpy.test()

Out of several thousand small tests I found this one error -- perhaps its
not really an error?

 This doesn't look serious but it can be bothersome when one is trying to be
sure that the installation is as good as possible.

Not sure if it matters, but my compiler is gcc-4.4.1 and I'm using
gfortran.  Both were wrapped with mpich2.

Regards,
John
