[Ros-release] OpenCV and Broken Electric Debs

Hi Chad,

Thanks for the heads up.  We did identify an issue in the SSE acceleration
as mentioned in many of those questions.  We rereleased opencv with fewer
patches.  The new binary got into our build pipeline but not into the
public facing repo.  I just resynced the repos and I think it should be ok

I don't know what's up with the debbuild status page.  I'll look into that
on Monday.  In the mean time, if you're curious you can generate a local
copy of the debbuild report with the following command assuming you
checkout the ros_release stack.

rosrun rosdeb list_missing.py electric --allhtml -o electric.html

If there's still a problem with installations please let us know,
