poudriere: Ports a01debe78c6a results in failure: (devel/py-zope.configuration): Error: devel/py-zope.configuration depends on nonexistent origin

On our poudriere build hosts poudriere fails out of the blue with the error shown below.

I have no clue how to fix this problem. Even deleting the whole "All" folder (ergo:
purging all built pkg packages) does not have any effect.

I'm not familiar with the depedencies within the ports tree and how they are managed, it
seems something serious affecting poudriere only (usual/traditional make on the ports
tree seems to work).
