The unison port has recently been upgraded from 2.13 to 2.27. The
problem is that the protocol has changed between these versions,
and unison 2.13 can't talk to unison 2.27:

  http://trac.macosforge.org/projects/macports/ticket/14172

The only solution that can work in every case (because users may need
to do synchronization with machines that only have 2.13 and machines
that only have 2.27) is to install the two binaries: unison-2.13 and
unison-2.27 (note: when executing the remote unison binary, unison can
automatically add its main version number thanks to the addversionno
option). So, I think that the best solution is to have a port for the
old version unison 2.13 (BTW, this is what Debian does for the 2.9
version and will probably do for the 2.13 version), which installs only
the unison-2.13 binary (alternatively, there could be a variant that
installs a "unison" binary too for those who don't need unison 2.27).
In this case, what should the name of the port be? unison-2.13?
unison2.13?
