Transferring this to the list, as the answer might benefit others:

First: the gfortran binaries I upload are for MacOS 10.4. They are 
linked from http://gcc.gnu.org/wiki/GFortran and a short installation 
instructions page can be found at 
http://gcc.gnu.org/wiki/GFortranBinariesMacOS . To be able to use the 
GNU Fortran compiler, you need the Apple Developer Tools installed 
(Xcode and friends); they're usually found on your Apple OS installation 
CD/DVD. If they're not installed yet (check the presence of a directory 
named Developer at the root of your disk.

Now, once you've downloaded the gfortran disk image, run the installer 
inside it. Upon completion, you will have gfortran installed inside 
directory /usr/local/gfortran, with a symbolic link for the compiler as 
/usr/local/bin/gfortran. To use it, open a Terminal and run gfortran by 
typing
> /usr/local/bin/gfortran myfile.f90 -o myprog.exe
Now, there's one more thing you need to do before your install is fully 
functionnal: update your cctools (the core of the developer tools) to 
the latest version, by downloading and installing 
ftp://gcc.gnu.org/pub/gcc/infrastructure/cctools-590.36.dmg

Once that's done, you should be fully able to use the compiler. Some 
more basic info about compiling mutliple-files projects can be found at 
http://gcc.gnu.org/wiki/GFortranGettingStarted
