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

--->  Staging blt into destroot

--->  Installing blt

- 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 blt with these commands:

%  man blt
%  apropos blt
%  which blt
%  locate blt
