The loading seems to be successful now, even though I haven't changed
anything--except that I did edit ess-site.el, adding and then removing
(edebug).
Could there have been some compiled version that got cleared out by
that process?
Some more details on the failure I was experiencing below.

I say the load was ineffective because
1) M-x ess <complete> doesn't get anything
2) M-x r is an unknown command
3) There is no *ESS* buffer
More recently it has been clear that ess-site.el was loading, because
when I put (edebug) in it a debugger came up.
