Unable to find libclang

What happened?

Currently I'm working on a Rust project that uses librocksdb-sys as a dependency and I'm unable to build the package when working inside a devbox shell though I can build it outside.

Steps to reproduce

1. Get a Rust project with librocksdb-sys as a dependency
2. Add rustup@1.26.0 and libllvm@17.0.6 to your devbox.json file
3. Try to build the project using cargo build

Command

[emlautarom1]

Note that /usr/lib64/libclang.so.17.0.6 exists and it's a proper shared object. The issue seems to be when trying to use it from the devbox shell. What I don't understand is why is it picking up the native one instead of the one stored in the Nix store.

Also having this issue.

Apparently there's a nix hook rustPlatform.bindgenHook but its not clear how to instruct devbox to use hooks.

Worse than that, now my environment outside of devbox also fails until I restart my shell
