Hi Andras,

The (horrible!) workaround I use for the moment is to use
libqt4-maemo5(-*) packages in both scratchbox and on-device. This
means that to compile in scratchbox, you will want
/opt/qt4-maemo5/bin/qmake, not just qmake, otherwise your app will use
the /usr/lib/ Qt which isn't what you want.

Obviously this isn't perfect, but it should get you by. Once 1.2 is
publically released, obviously, you should revert to using the normal
Qt packages.

HTH,
