You could always write a small bit of code to test .Machine 
$sizeof.pointer and put it in the .First function.

My method is to label my GUI's so I pick the right one.

A very similar question was very recently (this morning, in fact)  
posed on the r-Mac-sig-list and the answer by Simon Urbanek is that  
there is no packaged version of R 2.9.2.

per Urbanek:
"The reason I said take 2.9.0 was because it's the fool proof method.  
[I don't have an installer for 64-bit R 2.9.2 yet because it's not  
automated due to changes in the PM]."

You have already been given advice about the order of installation of  
the packaged version and detailed instruction on how to update to  
2.9.2 (was all that typing and testing in vain?),  as well as advice  
to post such questions as this one on the correct list. Maybe you  
should (re-?)read the Posting Guide.
