hmmm... there may be leakage from the lisp code for splus help into the
lisp code  for R help help; R shouldn't need the pager to be set, and so
seeing pager = 'sylnx -dump' is the probable cause of the error.  

Can you try a new emacs session, start R and then try C-c C-v?  (i.e. don't
start S).  Also, take out any settings for pager and help.pager from
your .emacs, if it still doesn't work.
