When I upgraded from Ubuntu 8.04 to 8.10 it broke my Numpy install (mighty irritating). I haven't looked in detail, but It seems as if some of the packages related to ATLAS have been renamed and the post-upgrade "cleanup" removed the development packages as it considered them obsolete.
I made sure that libatlas-base-dev and libatlas-sse2-dev (this machine supports sse2) were installed and was able to rebuild and install Numpy with no problems. I do not have an ATLAS environment variable.
