Did you follow instructions in

  http://math-atlas.sourceforge.net/errata.html#completelp

If yes, then what is the output of
  python scipy_distutils/system_info.py
?

Hmm, in scipy/INSTALL.txt is written that SciPy requires ATLAS 3.3.14 or
newer. Is anyone using ATLAS 3.2.1 succesfully with scipy?

That's because you are trying to import scipy from its source directory.
Change to another directory and try again.
