Try this:

file_search_maxima : append
(["/usr/share/maxima/.../share/contrib/Zeilberger"],
file_search_maxima);
load(LOADZeilberger);

For the "/usr/share/maxima/..." you will have to put whatever
precedes share/contrib/Zeilberger on your system.

I recommend pretty strongly that you try to get a newer version
of Maxima -- there have been many improvements since 5.9.2.

No, the Zeilberger package has its own implementation of
the Gosper algorithm, it doesn't call nusum.

Hope this helps
