And because does not list libxcb-xinerama0-dev but libxcb-xinerama-dev (without the trailing 0) it's very easy to accidentally not install..

Thanks for the hint

Is there a way to find out whether QtX11extras will be built without having to wait two hours to see if PyQt5 can be built?
I tried to run .configure <many args> but it seems to not reconfigure anything and there seems to be no information about x11extras..
