Good morning to everyone.
If you are building the new 4.0 series on Debian/Ubuntu it is also necessary portaudio-dev and libqt-gl-dev for the Qt-gui interface.
They are installed?
Try to re-configure.

Perhaps you use octave 3.8.1 from Ubuntu repository. In the case, only run time libraries for Qt are installed.
Please install dev package for qt and qscintilla.
$ sudo apt-get install libqt4-dev libqscintilla2-dev
and try to build again.
