I did rebuild the packages now. The scripttools indeed only produced a
warning. However, on pre 4.5 versions (Ubuntu hardy and intrepid) the
build failed with several errors similar to:
src/TeXDocument.cpp:2173: error: invalid use of incomplete type 'struct
/usr/include/qt4/QtGui/qtableview.h:51: error: forward declaration of
'struct QHeaderView'

Curiously, the 4.5 builds (Ubuntu jaunty a karmic) succeeded without
problem. Apparently, some Qt includes have changed in that version. I
patched the build system now by simply explicitly #include'ing
<QHeaderView>. I suggest you also do that in the repository. With that,
the builds succeeded (finally ;)).
