- install conf-llvm-static 20 [required by llvm]
- install csexp 1.5.2 [required by dune-configurator]
- install ctypes 0.24.0 [required by llvm]
- install dune 3.21.0 [required by ctypes]
- install dune-configurator 3.21.0 [required by ctypes]
- install integers 0.7.0 [required by ctypes]
- install llvm 20-static (pinned)
- install ocamlfind 1.9.8 [required by llvm]
- install stdlib-shims 0.3.0 [required by integers]
The following system packages will first need to be installed:

<><> Handling external dependencies <><><><><><><><><><><><><><><><><><><><><><>
opam believes some required external dependencies are missing. opam can:
> 1. Run yum to install them (may need root/sudo access)
2. Display the recommended yum command and wait while you run it manually (e.g. in another terminal)
3. Continue anyway, and, upon success, permanently register that this external dependency is present, but not detectable
4. Abort the installation
