Comment:

 I checked on Fernando machine: the problem is that you built numpy and
 scipy with g77, where atlas was built with gfortran. I built numpy adn
 scipy both with g77 and gfortran, and I do get those errors with g77, but
 not with gfortran.

 To check whether you mixed g77 (scipy) and gfortran (atlas), you can use
 ldd on any extension using lapack, for example scipy/linalg/flapack.so. If
 you see both libg2c.so (g77 specifi) and libgfortran.so (gfortran
 specific), you mix them, and this cannot work.
