 Replying to [comment:3 ryandesign]:
 > It is true that you must use the same version of unison on both ends of
 the connection. See #14172 for some previous discussion.

 It's also explained in the port's notes:

 {{{
 $ port notes unison
 unison has the following notes:
   Unison has always suggested using the same version across machines
   accessing the the same files. If you want to keep the previous
   version, you can reactivate the previous version; see:
