If you are able to use rpmdrake and are able to connect to the internet, go to google and type,
easy urpmi.
You will find a very good rpm download page where you can get ALL of the mdk packages along with updates, contribs, and plf's.
You should first do a,
urpmi.removemedia -a
to clear out all record of what you already have or the system thinks you were supposed to have before you start the downloads but it will give you even more packages than you get on the 3 cd's.
Have fun!
