To Reproduce

1. docker run -it --rm debian:bookworm-slim bash

2. apt-get update;
   apt-get dist-upgrade -y;
   apt-get install --no-install-recommends -y curl ca-certificates patch unzip bubblewrap git bzip2 gcc make libc6-dev;
   curl -sS -L -o /usr/local/bin/opam https://github.com/ocaml/opam/releases/download/2.1.5/opam-2.1.5-x86_64-linux;
   chmod +x /usr/local/bin/opam;
   opam init --bare --disable-sandboxing -n;
   opam switch create 5.0.0;
   eval $(opam env --switch=5.0.0);
   opam install --confirm-level=unsafe-yes liquidsoap ogg flac;

Expected behavior Liquidsoap from opam builds with ogg and flac support.
