No module named sets_ when running rd-start

[soltysh]

@ezio-melotti I didn't notice this until now that I'm building the openshift version of bpo, when I run rd-start on a clean fresh repo clone I'm getting this. I didn't catch it earlier beacuse I had sets_.pyc in place, when I removed it I'm getting the exact same error. Looks like we need an update, any ideas?

A fresh run didn't reproduce this for me; perhaps it's been fixed in the interim?
