[R-SIG-Mac] Mavericks/Snow Leopard package incompatibilities

[Brian Diggs]

I've seen a few messages about incompatibilities between the Mavericks 
and Snow Leopard builds of R. They have different binary build types and 
packages built for one can not be used for the other.

It occurs to me that it would be helpful if R would report when a 
mismatch happens between the version of R running and the version of R a 
package is compiled for. Looking at testPlatformEquivalence in library.R 
(in base), it appears this is the right place for this check to be made. 
However, I don't readily understand exactly what might be passed to that 
function or what the specific differences are in the version strings for 
these two build.

Does having this checked automatically seem like a good idea? If so, can 
someone who understands the finer points of the version strings make the 
proper enhancement?
