When Python 3.13+ is added to EL 9, virtualenv in EPEL 9 will look for the wheels in /usr/share/python3.13-wheels/ We need to add: Requires: (python3.13-pip-wheel if python3.13) Requires: (python3.13-setuptools-wheel if python3.13) And since we don't have python3.13-wheel-wheel we need to either backport https://src.fedoraproject.org/rpms/python-virtualenv/pull-request/133 (but adjust the Python version this applies to to 3.13+) or if that fails, package python3.13-wheel-wheel into EPEL 9 and add a requirement for that as well.
