How does one run rpmbuild -ba on the the Pello example in the python packaging guidelines ? The Pello.spec file appears under the heading Example spec file at: https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_exampl... In Pello.spec, the following lines appear: Version:        1.0.3 URL:            https://github.com/fedora-python/Pello Source: %{url}/archive/v%{version}/Pello-%{version}.tar.gz This indicates that the web address for the upstream source is https://github.com/fedora-python/Pello/archive/v1.0.3/Pello-1.0.3.tar.gz I placed Pello.spec in my SPECS directory, Pello-1.0.3.tar.gz in my SOURCES directory, and executed the command     rmpbuild -ba SPECS/Pello.spec from the rpmbuild directory and got the following result: ... snip ... Requirement satisfied: setuptools>=42    (installed: setuptools 59.6.0) Handling wheel from build-system.requires Requirement not satisfied: wheel Exiting dependency generation pass: build backend + RPM_EC=0 ++ jobs -p + exit 0 error: Failed build dependencies:         python3dist(wheel) is needed by python-pello-1.0.3-1.fc36.noarch ... Because the guidelines say pyhon3-devel needs to be list in BuildRequires, I checked that it is installed on my system: rpmbuild>sudo dnf install python3-devel ...
