Ocaml might be the most frustrating upgrade experience I've had. One updated package with an Ocaml update means I need to recompile all of the packages
Someone please implement a FUSE adapter for Google Drive in any other language 😭

This would probably be a perfect project for Rust but I have two other personal projects I'm not working on right now

Also I'd probably be an asshole and name it google-drive-rustfuse or something more assertive just to spite Ocaml and whoever thought libs compiled under a different bugfix release of the same compiler couldn't be compatible

Oh, not to mention half of the dependencies are now unmaintained on the AUR. Very cool

Now there are ocaml packages with exact version dependencies between AUR and official repos so it won't even let my system update wonderful

When your recommended upgrade path is to uninstall the package and all dependencies and reinstall, your fundamental architecture is broken.
This isn't just with major updates or breaking changes. This seems to happen with every dependency BUGFIX update.

This seems especially apparent when trying to fix these dependency issues without uninstalling. Some dependencies have to be updated before others. Hypothetically this could be fixed at the package manager level. Afaik however there are no source-install via official repos, and package managers shouldn't have to know the details of a package to install by source. That's literally handled by the scripts of the package itself

To be fair this is probably entirely because I'm trying to use it through the AUR. Ocaml does seem to have its own package manager, and that probably works fine. So considering, this is likely specific to *AUR* Ocaml packages, where maintainers aren't necessarily working in tandem.
