[SciPy-dev] Updated OS X build instructions -- test failures.

[Andrew Jaffe]

Hi All-

I've found the following test(10) errors under OS X (Bob Ippolito's 
Python 2.4.1). Test(1) succeeds. Should I be worried? Actually, it's 
gotten worse since version 1834: the mask failure is new.

In [1]: import numpy

In [2]: numpy.__version__
