Well, FWIW I can now verify that there are problems with third-party apps building out of the box since the Qt headers have moved from /usr/include/qt to /usr/include/qt3.
>From the kile build: checking for Qt... configure: error: Qt (>= Qt 3.0.3) (headers and libraries) not found. Please check your installation! Anyway, as I said earlier, the problem is that third-party apps ship a snapshot of admin/ that is not necessarily up-to-date with KDE CVS. It seems then that /usr/include/qt3 hasn't always been in the default search path for KDE3 includes. I'm not asking for the headers to be moved back, and packagers are presumably aware of how to fix the builds, but it's nevertheless worth being aware that some apps already in debian will break, and some of the numerous not-yet-packaged third-party apps won't build quite as smoothly out of the box as they used to. Ben.
