Upgrade to the latest: 4.2.0
Poudriere test builds on 11.1 (amd64,i386) and 10.4 (amd64,i386) both
py27 and py36 flvours.
No problem. I've a module I'm working on porting that lists the updated version in requirements.txt -- whether that is the version they actually need, or just what was available at the time
is another question.
The port in question is ultimately devel/py-molecule -- however I think that it has since dropped the requirement for pbr in favour of setuptools-scm. (I need to update the py-molecule port it seems)
