If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/gnat-gcc
%  sudo port install gnat-gcc  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching gnat-gcc
--->  Verifying checksum for gnat-gcc
--->  Extracting gnat-gcc
--->  Configuring gnat-gcc
--->  Building gnat-gcc with target all

--->  Staging gnat-gcc into destroot

--->  Installing gnat-gcc

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using gnat-gcc with these commands:

%  man gnat-gcc
%  apropos gnat-gcc
%  which gnat-gcc
%  locate gnat-gcc
