[PySide] Failure trying to build pyside2

[Filippo Rusconi]

Greetings, Fellow Developers,

I continue to try building pyside2 according to the instructions mentioned in my
earlier mail:

https://doc.qt.io/qtforpython/gettingstarted-linux.html

A recent upgrade in my Debian box had me hope that the initial failure would be
gone. Indeed, but no, I have another one :(

I had to divide the large output into two paste bins:

https://paste.debian.net/1166404/

and 

https://paste.debian.net/1166406/

Has anybody experienced this kind of build failure ? What is the typical setup
that works for building pyside2 from source ?

Sincerely,
Filippo Rusconi
