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/gcc42
%  sudo port install gcc42  
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 gcc42
--->  Verifying checksum for gcc42
--->  Extracting gcc42
--->  Configuring gcc42
--->  Building gcc42 with target all

--->  Staging gcc42 into destroot

--->  Installing gcc42

- 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 gcc42 with these commands:

%  man gcc42
%  apropos gcc42
%  which gcc42
%  locate gcc42
