Hmmm, that patch doesnt quite work for us locally at Imageworks. (I
think it's probably because we use a namespaced version of boost, and
the macro isn't quite right in our context). Let me see if I can find
a solution that works for both of us.

I've also been rethinking the use of boost within OCIO. Currently
there are only two things we use it for: shared_ptr and the unit test
framework. Given the issues that can occur when linking against
other apps the rely on different boost versions, boost may be a can of
worms worth avoiding, particularly considering that at this time it
may be a pretty simple dependency to remove.

Does anyone have any strong feelings (or experience) on this?
