I"m trying to do it Martin's way because I like to keep my
site-libraries separate from the R folders for ease of upgrade purposes.
I know have both R-2.6.1 and R-devel on my PATH. From the shell, typing
"R" gets me 2.6.1 because its first on my PATH; but from ESS now I can't
get either R to start.
How can I customize emacs exec-path? From what I have read, it is
initialized from the PATH variable.
