well, he said he used (GNU) Emacs 21.3 and indeed, that does
*NOT* yet have run-mode-hooks.

yes that will help.
However, I think we should ESS keep running with Emacs 21.x for
a little while.
ESS core *had* decided to no longer support Emacs 20 or earlier, but
we have kept 21.x in the list of supported Emacsen.
After a short look at the definition of run-mode-hooks (in Emacs 22.3)
I think it should not be hard to make ESS workable again for
Emacs 21.x, if necessary just by making it a no-op for 21.x
