If I understand the Leopard architecture correctly, you don't want to  
mess around with /etc/bashrc to set additional paths. Rather, add a  
new file to /etc/paths.d/ which contains _only_ the extra search path.  
This should be included automatically in $PATH when you start a new  
Terminal session, but won't work for R.app either.

This looks pretty wrong to me, although I'm not really familiar with  
Apple's property lists. You seem to assume that property lists  
understand bash's $XXX notation for variable interpolation, which I'm  
quite sure won't work. I suspect that you have to insert the FULL,  
EXPANDED path list here, as printed when you type "echo $PATH" in the  
Terminal.

Hope this helps,
Stefan
