[Numpy-discussion] numpy compilation question

Hello, 

I try to compile numpy-1.0b1 with blas and lapack support. I have
compiled blas and lapack according to the instrunctions in 

http://pong.tamu.edu/tiki/tiki-view_blog_post.php?blogId=6&postId=97 .

I copied the libraries to /scratch/python2.4/lib and set the
environment variables accordingly. python setup.py config in the numpy
directory then finds the libraries. If I then do 

python setup.py build

The compilation dies with the error message:

..

exit status 1

I try this on a dual processor Xeon machine with gcc 3.2.3 under an
old redhat distribution. Therefore using the libraries delivered with
the distro don't work as they are broken. 

At first I tried to compile numpy with atlas support but I got similar
problems. I have attached the full output of the failed build. I would
be very grateful if somebody with a little more experience with
compilers could have a look at it and maybe point me in the right
direction.

Many thanks in advance,

Hanno
