[Distutils] namespace packages broken in ubuntu with zc.buildout 1.5?

[Jim Fulton]

See the posts from Felix Schwarz here a few days ago.  It looks like
he ran into and
debugged the same issue.  I haven't had a chance to wade into it. (I can't
say I'm looking forward to it.)

I'll try to get up to speed on this this weekend.
