So have some make-festing we found out the source of the problems:

- HACKING.txt was missing python-oops-twisted in the list of runtime
packages.
- dependencies are resolved from the eggs cache first, so make sure you
nuke that one (look in ~/.buildout/defaults.cfg) for the location,
otherwise it sits in eggs/ in the source directory by default.

Once that extra package is installed and the existings eggs cache
removed, every things seems to be working properly.
