I had to change lapack_libs and lapack_dirs in addons.py to read: 

  lapack_libs = ['lapack', 'f77blas', 'f2c', 'cblas', 'atlas', 'm']
  lapack_dirs = ['/usr/local/lib/ATLAS']

I have all my .a files in /usr/local/lib/ATLAS so I can control which ones I'm 
actually linking against.

mosel ~ % ls -l /usr/local/lib/ATLAS
total 14608

(and yes, I get a significant speed boost from ATLAS)
