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

--->  Staging avr-binutils into destroot

--->  Installing avr-binutils

- 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 avr-binutils with these commands:

%  man avr-binutils
%  apropos avr-binutils
%  which avr-binutils
%  locate avr-binutils
