I would suggest gcc44. I think gcc45 has been released officially (and is
no longer experimental), but whether or not macports has the newest release,
I'm not sure (and whether it's bug-free is even less sure). GCC 4.4 is also
known to be quite stable, and has been the most thoroughly tested with
amber.
You can install what you need via
sudo port install gcc44 +gfortran
Good luck!
