Fails to build on Endevour

[agent-squirrel]

When installing from the AUR on Endevour (Arch) the following error occurs with both the stable branch and git release.

==> Entering fakeroot environment...   
 ==> Starting package()...
 dune install: option `--libdir': the path must be absolute to avoid ambiguity
 Usage: dune install [OPTION]... [PACKAGE]...
 Try `dune install --help' or `dune --help' for more information.
 ==> ERROR: A failure occurred in package().
    Aborting...
  -> error making: ocaml-cryptokit

Possibly breaking change with dune?

I have the same error in Manjaro
