flux-core: 0.67.0 builds failing due to Python environment

[vsoch]

@trws does this look salient to you? Why would we need to define these python envars in spack now?

[trws]

That's a new one on me, maybe it's having trouble getting them from the python it found, but I don't know what it tries that fails to get it to that point. Maybe this is another bit of fallout from setup tools not being there by default without request anymore?

I've been burned by that for two other projects this week! I don't have any ideas either, so I'll give that a shot. The ubuntu images are definitely latest so we are getting a newer Python. I can't reproduce the error locally so having trouble debugging. I'll try installing setuptools and report back.

Same bug, so wasn't that!

What config or base produces this? I could try and poke at it but just realized I'm not sure where it came from.
