That's interesting, I often find the tooling one of the best things that FP languages offer. In OCaml for instance I found Dune to be fantastic and extremely intuitive. Another very good experience I had was with Elixir and Hex. In Haskell I personally think that there are indeed quite a few things that could be improved around build system and packaging, but overall it's not really that bad once you learn the quirks.
Teaching anything beyond dune build or opam install feels out of place for a beginner tutorial.
However, there really should be more examples of “how to do X in dune”. It took me a bit to learn how to pin a git repo for local use and installation.
