[Numpy-discussion] Problem building 1.3.0 on x86_64 platform

Hi,

I am attempting (and failing...) to build numpy on a Scientific Linux  
4.6 x86_64 (essentially RHEL I believe) with Python 2.4 (i386). The  
machine has the following Python RPM installed:

python2.4-2.4-1pydotorg.i386
python2.4-tools-2.4-1pydotorg.i386
python2.4-devel-2.4-1pydotorg.i386

And also has gcc, g++ and f77 installed.

Running python setup.py config appears to be successful, with lots of  
warnings abougt ATLAS, BLAS etc not being available (this is fine, I  
just want numpy for the array handling features used in matplotlib).  
However, the build fails (following doesn't show missing library  
warnings, as above):

------------------------------------------------------------------------------------------------------

I note that the distribution directory being created is build/ 
src.linux-x86_64-2.4 - not i386. Can I force the architecture in the  
configure step, as it appears this would be the problem (hinted at by  
LONG_BIG wrong for platform error).

Any hints gratefully received!

Regards,
James.
