Did you set the ATLAS environment variable (I don't know if it looks in common places or if it always requires ATLAS to be set)?
( scipy/system_info.py looks ATLAS libraries in all common places such as /usr/lib,/usr/local/lib,/opt/lib,/usr/lib/atlas,<sys.prefix>/lib, etc etc (but not necessary in the given order) and setting ATLAS environment variable is *not* an requirement. ATLAS environment variable can be useful only if 1) ATLAS is installed in a rather uncommon place, 2) or if one has different ATLAS libraries in the system and then ATLAS environment variable can be used to specify which one scipy should use. However, scipy/system_info.py refuses to find ATLAS libraries that are incomplete. The definition of completness is as follows: The following four files liblapack.a, libf77blas.a, libcblas.a, libatlas.a must exist in the *same* directory and the size of liblapack.a should be around 6MB (that is, the instructions in http://math-atlas.sourceforge.net/errata.html#completelp are succesfully applied). If any of these conditions is unsatisfied, expect problems when importing scipy. ) Pearu
