This is caused by an ocaml compile error:

File "freetennis.ml", lines 767-770, characters 26-8:
767 | ..........................struct
768 | 			      type t = int
769 | 			      let compare = compare
770 | 			  end..
Error: Signature mismatch:

         end
       is not included in
         Map.OrderedType
       Values do not match:

       File "map.mli", line 54, characters 4-31: Expected declaration
       File "freetennis.ml", line 769, characters 13-20: Actual declaration

Fixing this goes beyond my non-existent ocaml knowledge, so I hope that one of the 2 people in the Cc of this bug can help fix this.

freetennis-0.4.8-ocaml-4.12.patch

This patch fixes the bug.

The problem is that the code opens the List module at the top, importing
every symbol from List into the namespace.  This is generally bad practice.
Recently List.compare was added to OCaml, which shadows the normal
compare function, and this causes the error you saw.

We could explicitly change every call to compare to Stdlib.compare, but
I felt it was better and a small patch to only import the List symbols
which are actually used.

Change to OCaml: https://github.com/ocaml/ocaml/pull/9668

BTW this could also be written like this, although that would
make the code depend on a very new OCaml only:

let length, hd, append, mem, filter = List.(length, hd, append, mem, filter)

Dear Maintainer,

your package has an open Fails To Build From Source bug for Fedora 35.
Action is required from you.

If you can fix your package to build, perform a build in koji, and either create
an update in bodhi, or close this bug without creating an update, if updating is
not appropriate [1]. If you are working on a fix, set the status to ASSIGNED to
acknowledge this. If you have already fixed this issue, please close this Bugzilla report.

Following the policy for such packages [2], your package will be orphaned if
this bug remains in NEW state more than 8 weeks (not sooner than 2021-09-23).

A week before the mass branching of Fedora 36 according to the schedule [3],
any packages not successfully rebuilt at least on Fedora 34 will be
retired regardless of the status of this bug.

Richard, thank you for the patch.

I'll prepare a new fixed package with the patch soon.

Fixed and build for rawhide, closing.
