[64studio-devel] 2.1 pre7 fails form 2.0 stable

[Quentin Harley]

I have installed a system, and upgraded the normal way - it fails with 
the following message.

The following packages have unmet dependencies:
  hpijs: Depends: gs-gpl (>= 8.01-5) or
                  gs-esp (>= 7.07.01-8) or
                  gs-afpl (>= 7.04-2)
E: Error, pkgProblemResolver::Resolve generated breaks, this may be 
caused by held packages.
tasksel: aptitude failed (255)

What could be the problem?

Cheers,
Quentin
