Far and away the easiest solution is to install Gentoo Linux.  All you need to 
do under gentoo is to add the "lapack" useflag and then "emerge numpy".  Gentoo 
will automatically install ATLAS/LAPACK by default, compiled according to your 
settings, and then compile NumPy to use that LAPACK.

As others have noted, running linux in a virtual machine under Windows may still 
be faster and easier than trying to configure a working installation in Windows. 
  This is especially true with coLinux, which has near-zero overhead.
