%  cd /opt/local/bin/portslocation/dports/cups-pdf
%  sudo port install cups-pdf

--->  Extracting cups-pdf
--->  Configuring cups-pdf
--->  Building cups-pdf with target all

--->  Staging cups-pdf into destroot

--->  Installing cups-pdf

- 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 cups-pdf with these commands:

%  man cups-pdf
