pbr is usually in nativeBuildInputs and not a run-time requirement. setuptools are also not mention in [requirements.txt](https://github.com/mongomock/mongomock/blob/3.23.0/requirements.txt]

That depends on the usage. If pbr is used in the program itself which some openstack things do then it needs to be propagated.

I haven't found any other reference to pbr except here
I'm not familiar with pbr, but looking at the documentation it seems, it is mainly (only?) used at build time.
I think its save to put it under nativeBuildInputs
