This is up to date with git master of yesterday and includes
the ocio-based lut docker. I tested on a clean centos5 64 bit vm and everything worked.

To make the lut docker work, you need to have an OpenColorIO configuration
available. See http://opencolorio.org/configurations/index.html for
downloads.

Please report any issues you have with it: as I've said before, it hasn't
been used for real yet, so I am sure there are bugs and oversights.
