Hmm, possibly? I cherry-picked the patches to sumo and saw this missing
dependency in my container.
Did poky master switch from using host python to native after sumo?
poky uses host python for some things and native python for other things. Generally where 'core python' is enough then we use the host python, but when additional libraries are needed, then native python plus those libraries is a better choice, as this doesn't require adding to the required host packages list, and allows better control over how they're built.
