utop.2.9.1 fails to run on 5.0.0+trunk

[kayceesrk]

I am observing the following utop failure with 5.0.0+trunk OCaml.

• OS: macOS Monterey 12.2.1
• Arch: x86-64 (Intel Core i7)

% opam update
% opam switch create 5.0.0+trunk --repo=default,alpha=git+https://github.com/kit-ty-kate/opam-alpha-repository.git # install 5.0.0+trunk compiler
% opam install utop # installs utop.2.9.1
% utop
Fatal error: cannot load shared library dllunix
Reason: dlopen(/Users/kc/.opam/5.0.0+trunk/lib/ocaml/stublibs/dllunix.so, 0x000A): symbol not found in flat namespace '_caml_alloc_2'
zsh: abort      utop

Not sure if this was a compiler issue or an utop issue. I thought I would start here.
