@GrahamcOfBorg build ocamlPackages.hxd ocamlPackages.melange ocamlPackages.ocplib-simplex

This breaks hxd tests (possible workaround: disable them).

For some reason, the dune cache is enabled, and there seems to be an error that cannot create a directory for it. I don't usually use Nix and don't know how to work around this. Can you help me?

@vbgl Isn't this possible for all packages using dune?

@GrahamcOfBorg build ocamlPackages.patdiff

Other newly failing OCaml libraries: ocplib-simplex, melange.

ocplib-index can be fixed using the following patch:

@vbgl Can you add commits to this PR? I'm completely new to the Nix ecosystem and still don't understand which packages are broken and how.

[vbgl]

I’ve just done it and included in this branch commits from other PRs (#362572 & #363369).

[smorimoto]

Thanks a lot!
