There is an unofficial, experimental R 2.2.1 release for MacIntels  
available already (see the CRAN OS X page at the bottom - Jan kindly  
posted the direct link). The R.app GUI is in fact shipped as  
universal binary since 2.2.1.

The reason for the Intel build being experimental is that it doesn't  
pass make check. The compilers (both Apple gcc and Intel) still seem  
to have bugs that cause them to miscompile code.

However, there is a light at the end of the tunnel - just now I was  
able to compile R for MacIntel that is much closer to passing make  
check ("only" one part of one check failed), so I expect to have more  
serious binary sometime next week.
