Disclaimer: I usually build ATLAS and LAPACK from source, I've
never really played with the netlib BLAS much.

liblapack.a may have certain BLAS functions inside the archive (I think)
if you installed ATLAS packages from your distribution. 
I'd recommend a clean LAPACK as well, and building numpy and scipy 
against the same set of libraries, just to be safe... From show_config()
it looks like everything should be in order, I think.

Are you getting the exact same errors after building against your
source built BLAS?
