Hi, SciPy now supports also ATLAS 3.2.1 (because that seems to be the latest ATLAS version for most Linux distributions). To enjoy this support, one must 1) set atlas_version_pre_3_3=1 in the header of scipy/linalg/setup_linalg.py 2) remove scipy/linalg/clapack.pyf 3) rebuild/reinstall scipy. Regards, Pearu
