Hey, For what it's worth, these 2 attached patches allow to compile on el6 (at least few weeks ago, did not try again just now).

Subject: [PATCH 2/2] Remove duplicate typedef
This fixes compilation on el6. This is achieved by moving the most problematic
typedef to a red-types.h header. Ideally, it will go away once we have put some
order in the header content/API/... For example, StreamAgent would be better as
an opaque type.
