Sorry, I've obviously overlooked something, but maybe I have also discovered a 
bug. I've just removed atlas/blas/lapack, updated scipy_core from svn, 
removed my build and site-packages/scipy directories, and tried to build 
scipy_core. Here is a warning message I get toward the end of the build and 
install processes:

and here I try to import scipy:

In [1]: from scipy import *
