Hi, I'm attempting to install numpy/scipy on my computer. I've installed lapack / atlas and have the following libs on my system: atlas-lapack /usr/lib/libatlas.a atlas-lapack /usr/lib/libcblas.a atlas-lapack /usr/lib/libf77blas.a atlas-lapack /usr/lib/liblapack.a The site.cfg reads: [atlas] library_dirs = /usr/lib/ atlas_libs = lapack, blas I'm having serious problems getting the numpy install to find the atlas and blas libraries: Any tips would be greatly appreciated. Thanks Todd heres the output of $ python setup.py config_fc --fcompiler=gnu95 build Running from numpy source directory.
