For those of you fortran heads, here's good news. FSF GCC now officially supports Darwin/OS X, meaning that you can grab latest source at gcc.gnu.org and build a version of gcc, including fortran (g77), on your OS X box.
Although I don't personally use fortran, this would be a breakthrough for scientists and engineers who use Macs and have *a lot* of fortran libraries. Read yourself Stan Shebs' comment at darwin dev list.
Cheers
