Apparently, the flake runs bun install one way or another without consider if bun is locally installed.

bun requires a CPU with AVX extensions to run - hence the illegal instruction error message. You can try overriding the bun version to baseline, but according to nixpkgs even that will have issues

My CPU is a Sandy Bridge generation. It has AVX support (256-bit SIMD). I'll do some research to see what I can do, because I can't acquire new hardware for now.
