title: Does Python SciPy need BLAS?
body: <pre><code>numpy.distutils.system_info.BlasNotFoundError: 
      Blas (http://www.netlib.org/blas/) libraries not found.
      Directories to search for the libraries can be specified in the
      numpy/distutils/site.cfg file (section [blas]) or by setting
      the BLAS environment variable.

  <p>Which tar do I need to download off this site?</p>
  
  <p>I've tried the fortrans, but I keep getting this error (after setting the environment variable obviously).</p>
