that wouldn't have been the best solution, but it was easy to
fix and is already committed in the ESS development sources.
Jianjie, if you can,
delete <ESS>/lisp/ess-mode.elc if it exists, and
apply the following patch to <ESS>/lisp/ess-mode.el
< (run-mode-hooks 'ess-mode-hook)

i.e., replace line 421 "(run-mode-hooks 'ess-mode-hook)"
with the new 4 line "(if .......)" statement above
(and if you know how, recreate the ess-mode.elc file).
In any case, the fix will be in ESS 5.3.11 which is to be
released "real soon now".
