What were you trying to do that didn't work?

I'm trying to build the python-steampunk-spotter package on EPEL-9.

What is the impact of this issue to you?

I'm unable to build the above package without patching it.

Please provide the package NVR for which the bug is seen:

python3-setuptools-53.0.0-13.el9.noarch

How reproducible is this bug?:

Always.

Steps to reproduce

1. Download python-pyahocorasick src.rpm from koji and the other two from review requests: #2283064 and #2283066.
2. mock -r epel-9-x86_64 --postinstall python-pyahocorasick-2.1.0-4.fc42.src.rpm
3. mock -r epel-9-x86_64 --postinstall python-detect-secrets-1.5.0-1.fc41.src.rpm 
4. mock --no-clean -r epel-9-x86_64 python-steampunk-spotter-3.3.0-1.fc41.src.rpm

Expected results

Successful package build.

Actual results

[...]
File "/usr/lib/python3.9/site-packages/pkg_resources/vendor/packaging/requirements.py", line 100, in __init_
