Comment (by kencu):

 I'm afraid the version of unison we offer is not happy with the version of
 ocaml in use. I am not fluent in camel-speak, so until some kind soul
 comes along, you are SOL for this one here.

 I see the gtk version on the github releases page:

 https://github.com/bcpierce00/unison/releases/download/v2.51.3/unison-v2.51.3+ocaml-4.10.1+x86_64.macos-10.15.tar.gz

 Is hardcoded to homebrew's parts:
 {{{
 % otool -L unison-gtk2
 unison-gtk2:
         /System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa
 (compatibility version 1.0.0, current version 23.0.0)

         /usr/local/opt/glib/lib/libgio-2.0.0.dylib (compatibility version

         /usr/local/opt/glib/lib/libgobject-2.0.0.dylib (compatibility

         /usr/local/opt/gettext/lib/libintl.8.dylib (compatibility version

         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1281.100.1)
 }}}

 but the plain version is not:
 {{{
 % otool -L unison
 unison:
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1281.100.1)

 % ./unison
 Usage: unison [options]
     or unison root1 root2 [options]
     or unison profilename [options]

 For a list of options, type "unison -help".
 For a tutorial on basic usage, type "unison -doc tutorial".
 For other documentation, type "unison -doc topics".
 }}}

 So the plain version works, if you download it from that (or one of the 20
 other links with different versions).
