I can start gnome-session, then mount CDROM #4 from 6 disk set, and then find the .gz and .dsc files. But that's as far as I can get. Which debian install untility will work with these packages? I could try to do it from command line if that would help. If I click on a .tar.gz file the Olde M$h*t way in the Gnome File Manager, the source code will display as text, but no install program gets initiated.
