I wonder if this could be because of the Qt 4.6 libraries and the upcoming PR 1.2 and the 'Autobuilder' of maemo.org already making use of them.... I can also see the app in Extras-Devel now, and I have the same error. I don't have the dependency error when installing the .deb file that I have packaged myself on my own environment... So the advise is probably to wait for PR 1.2 for 'normal' users (and let's not start a discussion about when that's going to happen as there are enough threads dealing with that already...). The adventurous can go ahead and install the .deb file manually
