[Numpy-discussion] Forcing the use of unoptimized blas/lapack even when atlas is present

[David Cournapeau]

Hi there,
   
    I am developing a building tool to automatically build the whole 
numpy/scipy/matplotlib set from sources including dependencies, and one 
of the problem I got is to force which blas/lapack version to use when 
building numpy and scipy.
    I thought that doing a BLAS=blaslib LAPACK=lapacklib python 
setup.config was enough when build numpy, but numpy still wants to use 
atlas. I would like to avoid using site.cfg if possible, as I want to 
build everything automatically,

    cheers,

    David
