 I am looking into moving to BuildBot from TeamCity.. Now I am trying to
 make BuildBot run on my Mac and everything is fine except that I am
 getting this:

 sudo buildbot create-master /Users/admin/buildbot/master
 Traceback (most recent call last):
   File "/opt/local/bin/buildbot", line 4, in <module>

     from sqlalchemy import exceptions as sa_exceptions
 ImportError: cannot import name exceptions

 I have tried the solution described here:

 http://stackoverflow.com/questions/17031471/why-buildbot-throw-
 importerror-cannot-import-name-exceptions

 but it did not work, probably it's outdated. My buildbot version is the
 recent 0.8.12, installed as per the instructions on the website.

 Please help! Thanks.
