Yes, see INSTALL.txt: section TROUBLESHOOTING, item (6)

This could be related to Python 2.2.2, not sure. On Python 2.3.1 this 
test succeeds.

I am not sure why these tests fail when switching Numeric 23.0->23.1.
I am using Python 2.3.1, Numeric 23.1, Atlas 3.2.1 and Scipy 
0.2.0__220.4275 and all tests pass OK. I'll later try earlier versions of 
Python...

Anyway, I don't see how the above failures could be related to
using different ATLAS versions as you originally suggested.
