Sorry but no. I don't want to wait and I suspect I don't have.
Debian and Ubuntu do still over ppc64le architecture packages for
PyQt5. So someone was able to build that. Why can't I do that?

Now you may ask why I don't use that packages from Debian/Ubuntu. Here
comes TravisCI on the stage. Travis does use python interpreters in
virtenv where the packages installed via (apt-get) are "ignored".
Currently I use kind of a "hack" for that
But I would prefer to (build and) install PyQt5 via pip.

Maybe the other way via "--global-config" is a better solution?

There are a lot of errors like this

Checking to see if the QtWinExtras bindings can be built...
Info: creating stash file
Project ERROR: Unknown module(s) in QT: core gui winextras widgets

What does it mean?

btw: I would suspect that "ERROR" messages will popup also with a
verbose flag.
