Comment:
python3-setuptools dependency is missing:
```
>>> import pikepdf
Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/pikepdf/__init__.py", line 19, in <module>
    from ._version import __version__
  File "/usr/lib/python3.10/site-packages/pikepdf/_version.py", line 7, in <module>
    from pkg_resources import DistributionNotFound
ModuleNotFoundError: No module named 'pkg_resources'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.10/site-packages/pikepdf/__init__.py", line 21, in <module>
    raise ImportError("Failed to determine version") from _e
ImportError: Failed to determine version
```
