lapack_src_info:
( src_dirs = /var/tmp/src/lapack:.:/usr/local/src:/var/tmp/src )
( paths: /var/tmp/src/lapack/LAPACK/SRC )
( library_dirs = /usr/local/lib:/usr/lib )
  FOUND:
    sources = ['/var/tmp/src/lapack/LAPACK/SRC/sbdsdc.f', 
'/var/tmp/src/la ...
... CK/SRC/izmax1.f', '/var/tmp/src/lapack/LAPACK/SRC/dzsum1.f']
    language = f77

Meanwhile I have made so many modifications with respect to the setting 
of environment variables and site.cfg
that I cannot tell you what is going wrong. So I decided to use ATLAS again.
Actually, I was going to resolve the segmentation fault in 
symeig.test.test().
As you mentioned before it is not neccessary to build scipy against 
FORTRAN LAPACK/BLAS.
So, do you plan to include the symeig package in scipy ?
