The problem with the KDE packages is that there is one set of them
included in the Debian distribution and the KDE project also distributes
.debs. (Note, that we always appreciate it if other distributes their
programs in .deb!) 

Since both set of packages use the same package names you can't really set
up any dependencies/conflicts to avoid that a user has KDE packages from
different sets installed at the same time. 

Note, that I haven't thought about the details of implementation a lot
yet, but here are two `spontaneous' solutions:

1. Have the KDE packages check in their preinst script if our KDE packages
are currently present and refuse installation (together with an
explanation) in that case. 

2. Enhance dpkg' "Conflicts:" fields (or set up a new field) which allows
"Conflicts:" with a package coming from a certain vendor.

Does this help?
