Comment (by tardyp):

 The problem of such constant is that you have to put it on eight too, or
 the import will fail.

 What I do in my conf, is that I have a

 ninemigration.py in my config which does a

 {{{
 IS_NINE=False
 try:
     import buildbot.www
 except ImportError:
     IS_NINE=True
 }}}
