You'll need to provide a little more information.  I'm assuming that you have a
devstack setup that you're ./unstack,sh ; ./stack.sh to upgrade? and overtime
the repos are gettiing out of sync.

Can you explain what you're doing?

Also can you please provide the out of:
pip freeze | sort
for repo in /opt/stack/* ; do (cd $repo ; [ -d .git ] && git describe ) ; done

That will help us understand what you have and why the constratints file
appears to be ineffective.
