The issue Sean raised in the Nova review is:

  ubuntu quantal, debian unstable, and fedora latest all seem to
  have webob 1.1.1

Is there anyway we can make '>= 1.1.1' the requirement and keep all
projects happy?

Distro packagers - anyone know the reason why webob isn't getting
updated in distros?
