Old python version for pypi compilation for Mac?

[Trondtr]

Installing the hfst package on pypi does not work, probably because it is set up for python 3.6. and I have 3.10 and probably soon also 3.11 and whatever the future will bring.

This page: https://pypi.org/project/hfst/
says.

"For Windows and Mac OS X, we offer binary wheels on PyPI. Wheels are available for python versions 2.7, 3.4, 3.5 and 3.6."

So, with no help for 3.10+, my Mac tries to compile by itself, but fails.

The output given is shown in the attached file.
