IIRC, since my first install of rustup on NixOS and after switching to fenix, I have gotten weird outputs from rustc when running commands such as cargo build, or in general running rust-related commands that install crates.
When running for instance, cargo build --release, my output looks like:
rustc: /nix/store/ilfqlmd6npxh3zaszdj7dj7zy6w96gmi-zlib-1.2.12/lib/libz.so.1: no version information available (required by /nix/store/mw52brvx7b9hf6gjwnp1b45j0nlhw8xl-rust-nightly-default-2022-04-16/lib/libLLVM-14-rust-1.62.0-nightly.so)

*Rest of the commands "normal" output is here*.
The command runs successfully, although the output is very annoying, and I would like to understand it’s origin. Attempting to add to my environment packages zlib did not help.
Rust setup:
In environment.systemPackages

In inputs
