Well, it seemed to go okay after upgrading to 5.11.2, but after this I 
am trying to build PyQt5.11.2 and that fails with:

	Re: [PyQt] fatal error configuring PyQt5.11.2: Cannot open include file: 'QDataStream': No such file or directory

What an I missing? I configured Qt with:

	configure -mediaplayer-backend wmf -opensource -confirm-license -make-tool jom -nomake examples -nomake tests

I got the source from git and initiated the repository with:

	perl init-repository--module-subset=default,-qtwebkit,-qtwebkit-examples,-qtwebengine

Best regards,
Tim
