In summary, the apparent issue seems to have resulted from using `sudo
pip3 install PyQt5` at some point as the latest version of it depends on
Qt 5.7.1 while `sudo apt-get install python3-pyqt5` depends on Qt 5.6.1
and the symbolic link to `libQt5Core.so.5` points to 5.6.1.
Simply removing and purging packages and reinstalling does not easily
correct this.
The observations regarding building using Qt 5.7.1 are still valid and
don't seem to affect building using Qt 5.6.1.

Thanks Jürgen. I see your approach. I have done it with other
packages but am not sure why I cannot get `pyqt5-dev` and
`pyqt5-dev-tools` 5.6.1 version directly from the `repo` as it did
exist last year. That would be the simplest solution.
yakkety has pyqt5-dev-tools=5.7+dfsg-2. But it actually depends on
python3-pyqt5=5.7+dfsg-2, which in turn is depends on libqt5core5a (>=
5.6.0~beta) - which is libqt5core5a=5.6.1+dfsg-3ubuntu6~4 in yakkety
(see [0] ff)
So no need to downgrade pyqt5 - it's built against Qt 5.6.1.
PyQt5 or package `python-pyqt5` can be removed and installed with
`sudo pip3 install` using the Qt 5.6.1 `.whl` file.
Mixing debs and pip might create a mess. I'd avoid that. And given
the above,
there's no need to anyway.
