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/gcc40
%  sudo port install gcc40  
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 gcc40
--->  Verifying checksum for gcc40
--->  Extracting gcc40
--->  Configuring gcc40
--->  Building gcc40 with target all

--->  Staging gcc40 into destroot

--->  Installing gcc40

- 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 gcc40 with these commands:

%  man gcc40
%  apropos gcc40
%  which gcc40
%  locate gcc40
