Hi,

Sorry; my first message wasn't under 40 KB with the attachments, so
here's the same message but with the log files at
http://www.stat.washington.edu/~hoytak/logs.tar.bz2.


> Which ones ?

Sorry; ATLAS = 3.9.4 and lapack=3.2.  I'll give 3.8.2 a shot per your advice.

Fair enough.  In my case I was having some issues with 32 bit and 64
bit mismatches (I think that fftw defaulted to 32 bit), so I set the
flags variables.  I also wanted to get the extra few percent of
performance by using the tuning flags.  I'll back up a bit now before
playing with them now, though.

> First, can you try without any blas/lapack (Do BLAS=None LAPACK=None
> ATLAS=None python setup.py ....) ?

This now works in the sense that it doesn't hang.  I still get a
number of test failures, however (build + test logs attached).

Thanks a lot for the help!
