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

--->  Staging lzma into destroot

--->  Installing lzma

- 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 lzma with these commands:

%  man lzma
%  apropos lzma
%  which lzma
%  locate lzma
