[Numpy-discussion] Test failures on 2.6

I'm having almost exactly the same problem, but with Python 2.6.1,
Numpy 1.2.1, and Nose 0.11.3. Nobody responded to TJ the first time
around, so any advice would be greatly appreciated.

Thanks,
Brad

Hi,

I'm getting a couple of test failures with Python 2.6, Numpy 1.2.0, Nose 0.10.4:
