Great!

a) what is the entry for /etc/apt/sources.list?

The I can test a little

b) a next logical step would be to add meta-packages for

        - gap-minimal
                depending on gnustep2 package + subpackages for each GAP 
application
        - gap full (some more less essential packages)
                depending on gap-minimal
        - gsde
                depdendent on gap-minimal and some X11 setup and other libs and 
apps (e.g. window manager)

Then it becomes really user-friendly to install a full GNUstep desktop...

BR,
Nikolaus
