I'm not sure - it depends on whether Aquamacs allows you to set  
environment variables automatically (I'm not a Aquamacs user) - if it  
does, set R_LIBS accordingly.

I know you said you don't want to touch .Rprofile, but just in case  
you change your mind, it would make it much simpler. This is what I  
use to synchronize command line R with the GUI (in .Rprofile):

if (length(.libPaths())==1) .libPaths(paste(Sys.getenv("HOME"),"/ 
Library/R/",paste(R.version$major,as.integer(R.version 
$minor),sep='.'),"/library",sep=''))

The benefit of this is that this works with any command-line R,  
regardless how you start it (ssh, X11, Terminal, Emacs, ...).

You are probably using PostScript device by default. Set "quartz" to  
be your default device. Also I think you still have to load CarbonEL  
first (unless you're using R-devel).
