Nix setup issues

[VOID404]

Description

I am trying to run gpui-components on my NixOS. I tried using the provided flake.nix, but I encountered some problems.

$ nix develop

[void@bboy:~/Workspace/download/gpui-component]$ cargo run
error: rustc 1.87.0-beta.8 is not supported by the following packages:
  ashpd@0.13.2 requires rustc 1.92
  cosmic-text@0.17.2 requires rustc 1.89
  home@0.5.12 requires rustc 1.88
  oo7@0.6.0 requires rustc 1.92
  smol_str@0.3.5 requires rustc 1.89
  wgpu@28.0.0 requires rustc 1.92
  wgpu@28.0.0 requires rustc 1.92
  wgpu@28.0.0 requires rustc 1.92
Either upgrade rustc or select compatible dependency versions with
`cargo update <name>@<current-ver> --precise <compatible-ver>`
where `<compatible-ver>` is the latest version supporting rustc 1.87.0-beta.8

this can be fixed by a nix flake update, but there are still some problems.

note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

Looks like dynamically linked libraries aren't configured correctly.

Environment

• GPUI: main
• GPUI Component: main
• Platform: NixOS 26.05 (Yarara)

Steps to Reproduce

1. Go to the repo root
2. nix develop
3. cargo run
4. See error

Expected

I can build and run gpui-component-story in the nix dev shell.

Actual

Rust toolchain version is incompatible + dynamic libraries are not found.
