# gpg-agent is built separately from the rest of gnupg2 to enable gnupg 1.x
# users to use gpg-agent as well. gnupg2, however, requires gpg-agent to run,
# and so gnupg2 depends on gpg-agent.

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/gnupg2
%  sudo port install gnupg2  
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 gnupg2
--->  Verifying checksum for gnupg2
--->  Extracting gnupg2
--->  Configuring gnupg2
--->  Building gnupg2 with target all

--->  Staging gnupg2 into destroot

--->  Installing gnupg2

- 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 gnupg2 with these commands:

%  man gnupg2
%  apropos gnupg2
%  which gnupg2
%  locate gnupg2
