[Numpy-discussion] failure

[Gideon Simpson]

Installing on a Sun machine with Red Hat linux, I got the following  
error:

======================================================================
FAIL: test_umath.TestComplexFunctions.test_against_cmath

How would you recommend I troubleshoot this?  How seriously should I  
take it?

This is with a fresh Python 2.5.4 installation too.
