luaqt fails to build on Ubuntu

[hugomg]

I got a build error when I tried to build lqt on Ubuntu. The installed version of libqt4-dev is 4.8

This is the output from the build:

This is the same output, but filtering out hundreds of WARNING unknown directive '#' lines:

I'm not experienced enough with Qt to figure out what is the real problem here. The impression I have is that the qtwebkit_slot.cpp file is missing a #include <QDebug> but isn't that an internal Qt file?
