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/mapm3
%  sudo port install mapm3  
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 mapm3
--->  Verifying checksum for mapm3
--->  Extracting mapm3
--->  Configuring mapm3
--->  Building mapm3 with target all

--->  Staging mapm3 into destroot

--->  Installing mapm3

- 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 mapm3 with these commands:

%  man mapm3
%  apropos mapm3
%  which mapm3
%  locate mapm3
