Well, this is not what is suggests to me, but I don't use S-plus.
So, I could be wrong, I'll check into this more on Monday.  But, 
the main problem seems to be the places that xemacs users
are installing ESS.  There have been alot of recent examples of
this so I'm not picking on Fabio.  However, let's look at his
installation directory:
/opt/freeware/lib/xemacs/xemacs-packages/ess-5.2.11/lisp/ess

This looks like an xemacs package install, but it is not.  An 
xemacs package would place it's ESS lisp files in:
/opt/freeware/lib/xemacs/xemacs-packages/lisp/ess

In order to do that, you'd have to follow the ESS installation 
intructions.  Or, if you know a shortcut, you can just unpack 
the ESS release into:
/opt/freeware/lib/xemacs/site-packages/ess

I suppose the beauty of xemacs vs. emacs is that you can install
the sumo packages without knowing the details.  However, that
ease-of-use bites them when they try to install something else
since it requires some knowledge or reading the instructions.
