[users at bb.net] Buildbot on Mac OS X

[Craig Treleaven]

Just to be clear, two of us from the MacPorts project have said that we want to fix our port.  It appears that a fork of sqlalchemy-migrate has emerged that (presumably) works with current versions of sqlalchemy.  (With Python 3 support, I believe.)  Surely the Buildbot project would want to move forward with a module that is being supported rather than stick with an old version?  If that fork is incompatible with Buildbot, perhaps there is another, better version?

I don’t understand your comment "describe in the setup.py with appropriate version rules”.  

I’m not a Python guy—I’ve essentially gone down the rabbit hole trying to set up an OS X builder for MythTV.  ‘virtualenv’ is just another layer between me and the problem that I’d rather be solving.  It looks like I’m going to go that way for the sake of testing my build-slave but I do want to fix our buildbot port.
