Bug#597739: Salome: cannot load module salomeloader

[Adam C Powell IV]

Dear Alain,

Thanks very much for the information on this bug.

I think that since salomeloader is a script, maybe we can patch that
script to set the PYTHONPATH variable.  That way we don't htave to have
too many files in dist-packages, and a non-expert user can run it.

What do you think?
