Hi, I am having troubles build rpy in Fedora 33 and I am running out of ideas.

https://src.fedoraproject.org/rpms/rpy

An example of a failure is here: https://koji.fedoraproject.org/koji/taskinfo?taskID=48721928

The problem says:

error: attempt to use unversioned python, define %__python to /usr/bin/python2 or /usr/bin/python3 explicitly

But I have no idea where does this comes from. Does anyone have any idea of what is going wrong?

Hey José Abílio o/

This is https://fedoraproject.org/wiki/Changes/PythonMacroError

And in the spec:

# export PYTHONPATH=%{buildroot}%{python_sitearch}

There are several things at play:

- %{python_sitearch} is derived from %__python - commenting macros like this is not preventing them form being evaluated
