Make sure that the build does not use the pyx file from upstream. It

Cython in the build log. The file is probably generated by an older
version of Cython and that is causing you the problem.
Thank you, Lumír, for pointing me in the right direction.
The offending pregenerated C file was indeed in the source tarball along with a
precompiled library for good measure.
I was looking at the source on GitHub, which does not have
skmisc/loess/src/_loess.c. I'm sure that's what you meant. It's generated from
skmisc/loess/src/_loess.pyx
I have switched to the GitHub source tarball, which seems to be aimed at
developers, who like to build everything from scratch, and comes without
pregenerated files nor binaries.
However, I haven't been able to build the package, yet. It looks like the
tools/cythonize.py script, which is called from setup.py, generates output,
that throws off %pyproject_buildrequires:
No matching package to install: 'Processing'
No matching package to install: 'changed'
Is there a standard way of handling noisy scripts? Or am I just out of luck
using pyproject macros? Or, my bet, am I missing something?

Looking at the code, this happens because:
1) their setup.py uses subprocess

We might need a more robust way of redirecting all of stdout:

As a temporary workaround, you might need to sed/patch the prints away or
convince upstream to print status information to stderr.
Thanks, Miro, I managed to get past the build stage and opened a PR
upstream.
