Compile issues with dateutil in Yocto build (Sumo) on Ubuntu 16.04.07 LTS

[trmong]

I am getting some weird compile errors when I try to include dateutil package in my python build. This is Yocto (Sumo) build from meta-openembedded on an Ubuntu 16.04.07 LTS build environment. Says syntax errors. If I remove just the dateutil package it completes the build fine with all the other python and python3 packages. It fails the same in both builds (python and python3). I have tried 2.7.1, 2.7.5, and 2.8.2 all with the same failure.

Any suggestions would be appreciated.

I thought it may be the release of Ubuntu. I have now tried to compile on Ubuntu 18.04.6 LTS with the same result

This seems to be related to how they packaged dateutil. Presumably it's pulling in a version of setuptools_scm that doesn't work on Python 2.
