SyntaxError: invalid syntax during build

This happens with python3 (3.7) builds of mitogen 2.8 on Debian GNU/Linux "sid":

Ah Fedora is patching parts of it:

That's because of Python 3, hmm :) Probably the simplest fix is to rename those files from .py -- setuptools shouldn't be looking at them at all. They are only used on Python 2.4. This is a super easy fix, will have it in 0.2.10.

Apologies for the convenience and thanks for reporting

To be clear, the .py rename requires an accompanying code change in (I believe) ansible_mitogen/

[alexmyczko]

What I did is rm -rf */compat and then build. That is good enough?

FWIW seeing this on FreeBSD ports too, which builds both 3.x and 2.x python flavours.
