I know that other people won't have this problem.  I've been using Octave 
for many years and it always worked.  I'm just wondering if anyone here 
has an idea of what might be causing this problem.  I can have the 
sysadmin redo the installation, and maybe that will work, or maybe he'll 
do the same thing wrong twice.  That's why having a clue about the cause 
of the problem might help me.
