I did get a long slew of errors when trying to install python2.5-qt4-gui. It probably did not install correctly or at all. When trying to force install the packages (apt-get -f install python2.5-qt4-core python2.5-qt4-gui) it tells me that both packages are already the newest version. However, even outside the virtual N900, on the scratchbox command line, when I launch Python, I cannot import qt.
