[SciPy-user] installation problem

[Johann Cohen-Tanugi]

hmm I don't have this symbol in my version of this shared lib, and I am 
no expert here :) But did you make sure that you  compiled ATLAS and 
scipy with gfortran? I could imagine something like that happening if 
scipy was built with g77 and ATLAS with gfortran.... You can use the 
fcompiler option to setup.py to ensure that gfortran is picked up as the 
fortran compiler.
Maybe an expert will kick in here...
