Use a released version instead (1.4.1 is the last one as we speak).
Although we try to keep a relatively robust trunk, it does not have
the QA put in the releases.

If you install the atlas libraries in /home/jhtu/local/lib, you need
something like:

[atlas]
library_dirs = /home/jhtu/local/lib

in your site.cfg

I guess you meant python setup.py install ? there is no makefile in numpy

They are, but they are broken, as showed on the logs you posted. The
atlas libraries packaged by RHEL 4 (and even 5 IIRC) are hopelessly
broken, you need to build atlas by yourself - preferably into an rpm
if you want to deploy on a cluster if you have admin rights.
