Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
pluto-dcerouter: Depends: pluto-confirm-dependencies (>= 1.0) but it is not going to be installed
Depends: pluto-confirm-dependencies (< 1.1) but it is not going to be installed

Any ideas? This really looks like a great product, but even on a completely fresh Ubuntu 6.10 install, I'm having no luck.
