that's not sufficient.
You must add 'R-devel' to your path.

One standard way {using bash} would be to do 

cd
mkdir bin
cd bin 
ln -s ~/R/R-devel/bin/R R-devel

and make sure that your '~/bin' is part of your PATH.
E.g., by (do this and add it to your ~/.bash_profile  !) :

export PATH=$PATH:~/bin

I assume that's an Xemacs problem.  
Has anyone else seen this?

{yes; solution above}
