esp-clang (esp-idf 5.5.2): autoPatchelf fails due to missing libxml2.so.2

[Peter3579]

After recent updates (between esp-idf 5.5.1 and current HEAD), building esp-idf 5.5.2 fails during the autoPatchelf phase.
The lld binary in esp-clang-esp-idf-v5.5.2 depends on libxml2.so.2, but autoPatchelf is unable to satisfy this dependency and aborts.
This issue does not occur with esp-idf 5.5.1 using the same nixpkgs.

Error message:

auto-patchelf: 1 dependencies could not be satisfied
error: auto-patchelf could not satisfy dependency libxml2.so.2 wanted by /nix/store/mzmllx9dlbbyy1qi2i9mrsk7x9djc0hi-esp-clang-esp-idf-v5.5.2/esp-clang/bin/lld
auto-patchelf failed to find all the required dependencies.
Add the missing dependencies to --libs or use `--ignore-missing="foo.so.1 bar.so etc.so"`.
error: Cannot build '/nix/store/khmgyq0kr2gw49qik5winxpn39598mj6-esp-clang-esp-idf-v5.5.2.drv'.
       Reason: builder failed with exit code 1.

Additional context:

• nixpkgs-unstable (non-flake setup).
• nixpkgs-esp-dev imported via builtins.fetchGit without pinning to a specific revision.
• No recent nix-channel --update; nixpkgs remained unchanged while nixpkgs-esp-dev advanced.
• I'm using: https://github.com/mirrexagon/nixpkgs-esp-dev/blob/master/examples/shell-standalone.nix

pinning to the commit before 5.5.2 update worked for me

# A standalone shell definition that downloads and uses packages from `nixpkgs-esp-dev` automatically.

let
  nixpkgs-esp-dev = builtins.fetchGit {
    url = "https://github.com/mirrexagon/nixpkgs-esp-dev.git";

    # Optionally pin to a specific commit of `nixpkgs-esp-dev`.
    rev = "b7a2e7caf5b730948fbffeae10edd30d7ede1f83";
  };

  pkgs = import <nixpkgs> {
    overlays = [ (import "${nixpkgs-esp-dev}/overlay.nix") ];
    config.permittedInsecurePackages = [ "python3.13-ecdsa-0.19.1" ];
  };
in
pkgs.mkShell {
  name = "esp-project";

  buildInputs = with pkgs; [ esp-idf-full libxml2 ];
}
