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

--->  Staging arc into destroot

--->  Installing arc

- 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 arc with these commands:

%  man arc
%  apropos arc
%  which arc
%  locate arc
