    COLUMNS=120 dpkg -l | grep -i blas
    COLUMNS=120 dpkg -l | grep -i atlas

The atlas -dev package used to have a buggy shlibs file leading to insufficient dependency
information. Users could end up with an arbitrary atlas package, instead of the the correct
default blas package (which can then be transparently replaced at runtime simply by 
installing a matching Atlas package).    

Do you actually have an Athlon cpu? Else you need to replace your Atlas packages with 
appropriate ones.

This depends on which -dev package you have installed.
