Thomas, Benjamin,
It would be best to distribute pyqt-x11 on the pythonocc site.
Its too much of a hassle to build it I think, even though its more manageble
these days.
A separate installer for pyqt-x11 + pythonocc would be ideal.
Speaking about pyqt-x11, have recent builds got the scintilla editor?
I was trying avacado, but the scintilla ( Qscint.so or something... ) wasn't
part of my module.
Better luck for you Thomas?
