Well ......
The reason the package is in contrib is that we did not have the time so far to make sure it works with the 5-0 branch, as we developed it using the 5-0 HEAD in July 2003.
Timo wanted to work on this, but apparently he did not get around to do it so far.
You might want to contact C.R.Oldham or Brad Duell as they managed to get it installed. They said something about manually installing the dependencies.
In any case, I think we should use this thread to coordinate any work and success we had in getting the package to work with the 5-0 branch. Furthermore, anyone wanting to i18n this, is highly welcome as well (as this would allow us to move it to the offical tree).
