ocp-index 1.1.5 works with 4.04.0 ; the error, here, doesn't seem to be related with the OCaml version.
Package Pos is supposed to come from ocp-indent's parser modules, that ocp-index uses. Can you check what version is installed and if the installation seems consistent ?

Thanks!

I found your branch at git+https://github.com/hcarty/ocp-indent#sequence-ignore-extensions is based upon ocp-indent's master, and the package was still probably pinned on your side.
Current version on opam-repository is actually based upon the branch rewind, because we found some regression with @OCamlPro-Henry's new parser ; ocp-indent hasn't been ported to the master version yet. Unfortunately, @OCamlPro-Henry has been very busy recently and couldn't fix the regressions yet so that we complete the update.

Ah! Thank you very much - you're correct, I still had a version pinned based off of master.

I am getting this error too when compiling ocp-index-1.1.5 with ocp-indent-1.6.0 on NixOS:
