It's strange, it's like ModuleNotFoundError was not catched by the "except
ImportError".

What's the version of python?

Something is again unexpected here.

If you have the meson error, it should stop the build there with an error.
And the error is only raised when docs is enabled.

For me it doesn't continue:
$ make
...
../docs/meson.build:32:6: ERROR: Problem encountered: Install a Python 3
version of python-sphinx and the readthedoc theme

I am trying to reproduce.. I tried with  vm-build-openbsd, but it reaches
console read timeout error... Now trying with freebsd (looking for a mirror
for iso, because 40kb/s atm for me)
