[ESS] .emacs code no longer working

[John Maindonald]

I have just now installed Vincent Goulet's emacs for MacOS X.  
(I had been using Carbon Rmacs.)  I find however that various 
settings in my .emacs  \file no longer work.  

In particular, I had it set up so that I could type ESC-x R32 to get 32-bit R, 
R64 to get 64-bit R.  I can use only ESC-x R.   I am guessing that at least
part of the  problem is that ess-site is loaded before the following statements 
appear:

(setq-default inferior-R-program-name "R32")	    ; unix systems
(setq ess-r-versions '("R-2" "R32" "R64"))
(require 'ess-site)
(require 'ess-font-lock)

ESC-x font-lock-mode does not work; I get
<<<
Shell: /bin/bash
Warning: Login shell did not return environment.
0 environment variables imported from login shell (/bin/bash).
For information about GNU Emacs and the GNU system, type C-h C-a.
Unable to load color "darkblue" [2 times]

Thanks
