[CentOS] Evolution Updated RPM

I realize that the Evolution included with 4.3 is not really 2.0, but it is not 2.4/2.6 either. Has anyone out there tried or successfully updated Evolution to the 2.6 version (or even 2.4) on CentOS? The OS is doing great on the desktop, I am however trying to use a Scalix connector that relies on some major changes that were done around 2.4 version of Evolution and it's Data Server. I have done a bit of digging and so far, to update to Evolution 2.4+ you would need a newer form of glib2 installed, which at that point would be a core update. Anyone have any luck or advice on this? Perhaps someone got the Scalix connector working on older Evolution (which would be ok with me).

Thanks
