[SciPy-dev] Test failures for 0.5.2 on OS X

Hi folks-

I just installed numpy-1.0.1 and scipy-0.5.2 on a PPC G4 running Universal
Python 2.4.4 on OS 10.4.8.  numpy passes all tests, but scipy.test() reports
two warnings and three failed tests, copied below.  I do not know in what
situation the test failures should be of concern, but the check_dot failures
look pretty basic.  The warnings suggest two sets of tests were ignored.
