So I was able to compile bondi with a little help from my friend epilys.

It went a little something like this:

$ sudo apt install opam
$ opam init
$ opam switch create 4.06.1
$ opam install base
$ opam install ocaml-lsp-server
$ opam install stdlib-shims
$ dune build

I’m not certain stdlib-shims was required and the ocaml-lsp-server was for vscode integration (I think).
