MarsSeed [1] filed a deletion request for ocaml-lastfm [2]: This library no longer works, because dependency ocamlnet has been abandonware for years and is only compatible with Ocaml 4. Therefore the latest update to this PKGBUILD is dead-on-arrival. Last consumer of this library was liquidsoap, itself long broken, with a kind-of abandonware upstream and deprecated legacy dependencies that only work with Ocaml4. It got deleted from AUR recently (March 2024).
