ImportError: No module named migrate.versioning

[Hua Zhang]

I failed to use the latest devstack code (today, Aug 5, 2013) to install openstack in RHEL6.4.

Noted that there is a similiar bug https://answers.launchpad.net/nova/+question/146204, but it doesn't work for me, bellow is sqlalchemy-migrate info.
$ sudo pip-2.6 show sqlalchemy-migrate
---
Name: sqlalchemy-migrate
Version: 0.7.2
Location: /usr/lib/python2.6/site-packages
Requires: SQLAlchemy, decorator, Tempita, setuptools

from migrate.versioning import api as versioning_api

[stack@rbobo keystone]$ pip show sqlalchemy-migrate
---
Name: sqlalchemy-migrate
Version: 0.7.2
Location: /usr/lib/python2.6/site-packages
Requires: SQLAlchemy, decorator, Tempita, setuptools

which matches requirements.txt

Sorry - meant to add keystone, not replace devstack!

This must have been fixed elsewhere.
