Well, the Wiki says "Using gcc4 is currently discouraged unless necessary, because gfortran is not stable enough (yet). However, you are free to give it a shot (useful for 64-bit R - see below, or G5- optimized R - see OptimizingR)." so I would say it indicates the opposite ;). The situation got worse, in fact, because recent Apple build versions of gfortran don't compile at all. However, you can still use older versions of gfortran which (sort of) work. Incidentally, we have been chasing some nasty compiler bugs in gcc4 just last week, and the global consensus concerning gcc in general is still to avoid gcc4 on production systems (unless necessary, e.g. you can't get around gcc4 for 64-bit ppc version of R). Yesterday's Xcode update still contains 4.0.1, so I suspect that Apple is currently more focused on getting the Intel machines going...
