Comment:

 If you are on Yosemite wiki:howto/InstallingOlderPort for OCaml 4.01 and
 then forcing unison to build from source is the only option.  OCaml was
 already at 4.02 when Yosemite was released, so a macports version built
 with 4.01 has never existed.

 For older OS X releases, if you want the default variants you can grab
 unison at 2.40.102_1 from packages.macports.org and install the package.
 Trying to 'port install port @version' does not work, it will always
 install whatever the current latest version in the PortIndex is.

 This has come up in the past when Unison itself is updated and various
 distros update at different paces causing compatibility.  Nobody has
 volunteered to put in the effort to support more than the latest release,
 especially since upstream provides binaries you can download.  CCing mww
 since this is a request for supporting multiple parallel installs of OCaml
 at this point.

 I still think this is invalid from macports standpoint for a
 'nomaintainer' port unless we add multiple OCaml ports in which case I'll
 add variants.  It works correctly as long as both ends are built with the
 same OCaml release after the _2 revision.
