I guess I was forgetting that R itself used a multilib rather than a  
fat file structure.

I guess my suggestion might be better phrased.  In the 64 bit versions  
once they ship, it would probably be nice is on 64 bit capable Intel  
Macs if the operative arch defaulted to x86_64, which on G5 it  
defaulted to ppc.
