	Analysis Complete

	I've reviewed the http-nu repository and found the key insights for fixing the Darwin build failure in nixpkgs.

	Root Cause

	The libproc v0.14.11 crate (a transitive dependency via nu-system → part of Nushell) uses bindgen to generate Rust bindings from C code. Bindgen requires libclang to compile, but the current nixpkgs package
	definition doesn't provide it for Darwin builds.

	How http-nu Successfully Builds on Darwin
