You need to install a Fortran compiler. I do not have a Mac to go into an EXACT 
step by step installation, which is also dependent on the OS X release, but from 
the experience with ONE installation I have done on a researcher laptop, and on 
the Mountain Lion OS:

1) Install Xcode https://developer.apple.com/xcode WITH COMMAND LINE TOOLS 
enabled. In my case it did require FIRST the installation an THEN to enable the 
command line tools. After the installation, open up Xcode in your /Applications 
folder. You’d want to go to Xcode -> Preferences -> Downloads tab then install 
the “Command Line Tools.” After you’re done, quit Xcode.

2) Install Macports https://www.macports.org/install.php using the package 
installer.

3) Log out and login as administrator and open a terminal. Now you can access 
the port command, and you can install software.

port install gcc46
port install mpich +gcc46
port install netcdf +netcdf4 +dap +gcc46
port install netcdf-fortran +gcc46
port install grads +curl +netcdf +udunits +readline +gd2 +shapelib +wgrib2
port install ncview

Whit this you should have a "minimal" environment to compile the model following 
the User Guide for the GNU fortran compiler. Note that all this comes from my 
memory and some google search, I am not able to help more than this because I do 
not own myself a Mac.

Things obviously change if You want to use a different compiler, such as Intel, 
IBM, PGI, etc. Hope someone else on the list can share her experience on this.
