Oh, I bet libart is for libgnomeprint. The current packaging disables that, though I'd like to get that working eventually. I could use some help in getting instructions for all these dependencies - most are pretty easy rebuilds from Gutsy, but some have a few caveats. Join the Maemo Garage project if you can help with this - I think we have a wiki there maybe (?) or if not I know we have SVN that we can keep documentation in.
