Sorry Kovid. I thought I had the right versions of python-qt and iibqt installed, but I should have paid closer attention to the package information. Currently, though, libqt-4.3 conflicts with 4.2 in aptitude and there are a number of programs I depend upon for the latter, so I guess I'm going to have to just wait for the next update to Ubuntu until I can try out the beta gui.
Ah, well. Thanks for the help and patience.
