The real failure seems to be this:

What platform is this running on? Looks like linux? It looks like it's trying to set up the cryptography package and failing. I think this works ok in the infra.git repo, so not sure what's happening.

Yes, this is my Goobuntu workstation.

I can show you in person, if that's helpful.

Do you have libffi-dev dev installed? Does "sudo apt-get install libffi-dev" fix the issue?

I worked with dgarrett@ yesterday in person and got his recipes training. I don't think we changed any system packages to make it work, though.

The main fix was to stop using "build/scripts/tools/runit.py".

After that, everything was okay.

User error.
