I wanted to let everyone know that OCIO has been accepted into Fedora. I've already got packages working their way through the build system.
Thanks to everyone for helping me deal with all the Fedora specific problems! (i.e. bundled libraries)
Also, I'd like to build an EL6 package (Redhat/CentOS,SL) but it only has cmake 2.6 and OCIO requires 2.8. What particular parts of the configuration require 2.8 and can they be worked around?
