ATLAS is an optimized version of BLAS/LAPACK, and has nothing to do with python. You can't install it with easy_install, you need to build it by yourself. I would advise against using it unless you need fast linear algebra for big matrices. Building ATLAS is a pain, and is maybe the number one issue for newcomers who try to build numpy. You can always install it later if you want, David -- http://mail.python.org/mailman/listinfo/python-list
