Build fails with scons > 4.1

[pataquets]

If I set scons>=3.0.1,<4.2 in requirements.txt, build succeeds.
I've found plutinosoft/Platinum#18 while searching for a solution. I guess it has something to do with it.
Just in case, a temp fix PR will follow shortly.

Relevant build log (on a Docker build):
