For all this to work, these versions of R must be in Mark's
PATH when emacs is started, or, actually rather in
Emacs' exec-path variable at the time the ESS lisp code is
loaded.

yes. That's what Rich has been trying to help you with above

that's the R part - maybe even more easy for you.. :
I do similar things.
If all the R versions you use are good enough to have getRversion(),
then use that.
The help ?getRversion contains this as part of its
examples :
if(getRversion() <= "2.5.0") { ## work around missing feature
cat("Your version of R, ", as.character(getRversion()),
", is outdated.\n",
"Now trying to work around that ...\n", sep = "")
}
otherwise {for *old* versions of R}, you need
RVersion <- paste(R.version$major, R.version$minor, sep=".")
*and* then must be more careful with the if(.) but
if(RVersion == "2.6.1")
will also work and most '<=' or '>=' will work correctly as well

yes indeed
