Description of problem: Opam is missing a dependency on bzip2. This can cause packages to silently fail to install. For example, jbuilder.

Good catch! I'll add bzip2 as a dependency and rebuild.
No problem! I found it in a minimal fedora docker, which is not a normal environment. Happy to have helped. :)
