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/bzip2
%  sudo port install bzip2  
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 bzip2
--->  Verifying checksum for bzip2
--->  Extracting bzip2
--->  Configuring bzip2
--->  Building bzip2 with target all

--->  Staging bzip2 into destroot

--->  Installing bzip2

- 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 bzip2 with these commands:

%  man bzip2
%  apropos bzip2
%  which bzip2
%  locate bzip2
