It's hard to find the error in the voluminous Krita build log.

Here it is:

Googling for this error message from sip-generate.py, there is plenty of
discussion. For example, this thread:

It's okay if we can't fix it or don't want to fix it, and instead choose
to remove the relevant functionality. But did we try to fix it yet? Can
you take a look?
