Please check RPM packaged rpm OBS service. Link provides above.
As you can used python2 deps.
Need troubleshoot on your environment why generated so strange deps.
I recommend start troubleshoot from build master branch with out any your
modification
Then add one by one your change commit (like "git bisect").
And located what change introduce such behavior.
