Comment # 14 on bug 1200664 from Marcus R���ckert

What is the problem we try to solve:

1. Tumbleweed publishes
2. this triggers rebuilds of all the projects in the OBS where people might use
3. user runs "zypper dup" before those rebuilds are done.

now the user has packages that fulfill the Requires but do not give the user a
working package. This is something we can solve!

And FWIW: when I opened the bug we even still had packages in Tumbleweed that
were broken.

I am not tied to any specific solution. but a generic solution in the python
macros would be preferred so we dont have to fix N places.

And yet one of the main features for the OBS is that users can build their own
packages easily and should also not create broken packages just because we
change the default python version in Tumbleweed.
