The e-mailI sent about version numbers ;). OS X 10.5.n results in Sys.info()['release'] == 9.n and OS X 10.6.n in Sys.info()['release'] == 10.n because Sys.info() reports the Darwin version, not OS X version. Ken had 10.6.6 so incidentally that corresponds to Darwin (6+4).6 = 10.6 so the 6 there has nothing to do with the first 6 in 10.6.6  ;). Ah, don't we all love riddles? ;)
