I have a sort of  work around.  This is on Debian squeeze.
.emacs has
;use with --no-site
; must load new ess first to prevent system-wide one from loading
(load "~/ess-12.09-2/lisp/ess-site")
; next line gets the standard system setup
(load "/usr/share/emacs/site-lisp/debian-startup")

.bashrc has
# If running interactively, then:
if [ "$PS1" ]; then
    export EDITOR=emacs
    alias emacs='emacs --no-site'

I think debian-startup is the usual first step for site startup, at
least in the absence of actual code in the /etc/emacs/site-start.el.

The one problem I've run into is that when emacs is invoked by some
other process, e.g., svn commit, it still does site startup first and
produces a bunch of error messages.  Also, later commands in .emacs are
never executed.

export EDITOR=emacs --no-site
legal (maybe in quotes)?  That might fix it.

I also tried
(unload-feature 'ess-site t)
but that didn't quite work; ess-version remained the old one.
Various other libraries depend on ess-site (e.g., 50ess.el), but I don't
think they are features and I couldn't figure out how to unload them.

Yes, I'll ask the sysadmin again.  I thought it would be easy to install
a personal copy of ess.  As you all already knew, it's not.
