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/lua50
%  sudo port install lua50  
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 lua50
--->  Verifying checksum for lua50
--->  Extracting lua50
--->  Configuring lua50
--->  Building lua50 with target all

--->  Staging lua50 into destroot

--->  Installing lua50

- 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 lua50 with these commands:

%  man lua50
%  apropos lua50
%  which lua50
%  locate lua50
