These packages were never in a very usable state. They only (unfortunately) ended up in jessie because OpenChange and evolution-mapi rely on the samba4 libraries and so the source package ended up in unstable. We've been talking about removing the server packages from stable (wheezy) release for this reason.
With that in mind, I'm not sure how useful it is to provide transition packages, especially not very well tested ones. Cheers, Jelmer
