I'm trying to backport ocaml-dune on launchpad, but it seems the way ocaml-dune is set up makes this impossible; ocaml-dune build-depends on libcsexp-ocaml-dev <!pkg.ocaml-dune.nocsexp>, but ocaml-csexp depends on ocaml-dune (>= 1.11). Is there any way to (mostly automatically) backport ocaml-dune to focal i386, trusty, bionic, and xenial? (The ppa I'm attempting to do this in is here <https://launchpad.net/~jgross-h/+archive/ubuntu/coq-8.17-daily/+packages>.)
Best, Jason
