Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.


Relevant part (hopefully):
> make[2]: Entering directory '/<<PKGBUILDDIR>>/docs'
> sphinx-build -b html -d _build/doctrees   . _build/html
> Running Sphinx v4.5.0
> 
> Configuration error:
> The configuration file (or one of the modules it imports) called sys.exit()
> The following packages could not be found and are required to build the documentation:
>     * matplotlib !=3.4.0,!=3.5.2,>=3.1
> Please install the "docs" requirements.
> make[2]: *** [Makefile:44: html] Error 2
