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/gcc43
%  sudo port install gcc43  
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 gcc43
--->  Verifying checksum for gcc43
--->  Extracting gcc43
--->  Configuring gcc43
--->  Building gcc43 with target all

--->  Staging gcc43 into destroot

--->  Installing gcc43

- 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 gcc43 with these commands:

%  man gcc43
%  apropos gcc43
%  which gcc43
%  locate gcc43
