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

--->  Staging apt into destroot

--->  Installing apt

- 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 apt with these commands:

%  man apt
%  apropos apt
%  which apt
%  locate apt
