This looks like the following change in pip:

https://pip.pypa.io/en/stable/news/#v25-3

"""
Remove support for the deprecated setup.py bdist_wheel mechanism. Consequently, --use-pep517 is now always on, and --no-use-pep517 has been removed.
"""

https://github.com/pypa/pip/issues/6334


As a workaround, try building the package with PIP_NO_BUILD_ISOLATION=0 set -- that disables build isolation (which is a tad confusing, see https://github.com/pypa/pip/issues/5735).


Version-Release number of selected component (if applicable): 4.7-3.fc44

Steps to Reproduce: Build the package from distgit using our copr linked above. E.g.:

fedpkg --release rawhide mockbuild -- --addrepo=https://download.copr.fedorainfracloud.org/results/churchyard/pip-25.3/fedora-rawhide-x86_64
