TL;DR -- I used pourdriere to build a bunch of packages and ended up with a package for py-importlib-resources that thinks it is v0.0.0 instead of v5.4.0.

Help?  Thanks!

I have a system that is 

  - built from packages that
  - I build using poudriere
  - and portshaker, which blends in my port for zettarepl

I hadn't updated recently.

Today I stood up a new pkg builder using 12.3 and ran my various ansible playbooks to set it up.

I built all of my packages and used them to update my system.

When I try to run zettarepl I get the following crash.

```
% /usr/local/bin/zettarepl
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/pkg_resources/__init__.py", line 568, in _build_master
    ws.require(__requires__)
  File "/usr/local/lib/python3.8/site-packages/pkg_resources/__init__.py", line 886, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/local/lib/python3.8/site-packages/pkg_resources/__init__.py", line 777, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (importlib-resources 0.0.0 (/usr/local/lib/python3.8/site-packages), Requirement.parse('importlib_resources>=1.4.0'), {'jsonschema'})

During handling of the above exception, another exception occurred:

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'importlib_resources>=1.4.0' distribution was not found and is required by jsonschema
```

When I look in /usr/local/lib/python3.8/site-packages on the updated system it seems that importlib_resources thinks that its version number is 0.0.0.

   importlib_resources-0.0.0-py3.8.egg-info

I've poked around a bit but I'm not sure where my build went off the rails.

I'd welcome solutions or clues for where to look.

**Thanks!**
