[Twisted-Python] How to set up Twisted buildbot VM?

Hi, I tried to set up a VM to test changes to Twisted's buildbot. I did this: git clone https://github.com/twisted-infra/braid cd braid vagrant up fab config.vagrant fab config.vagrant base.bootstrap fab config.vagrant buildbot.install I got some errors at this point (see attached log). Any ideas how to get this working? Thanks. -- Craig
