I cannot figure - in any way - how to make my environment work. This is my flake:

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/release-24.05";
    powerlifted-flake.url = "github:peperunas/planner8";
    flake-utils.url = "github:numtide/flake-utils";
    poetry2nix = {
      url = "github:nix-community/poetry2nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, flake-utils, powerlifted-flake, poetry2nix }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        inherit (poetry2nix.lib.mkPoetry2Nix { inherit pkgs; }) mkPoetryEnv defaultPoetryOverrides;

        pkgs = import nixpkgs {
          inherit system;
          config.allowUnfree = true;
        };

        powerlifted = powerlifted-flake.packages.${system}.powerlifted;

        shellWithPkgs = packages:
          pkgs.mkShell {
            inherit packages;
            buildInputs = [
              pkgs.bashInteractive
              (mkPoetryEnv {
                projectDir = ./.;
                preferWheels = true;
                overrides = defaultPoetryOverrides.extend (self: super: {
                  gcs-oauth2-boto-plugin = super.gcs-oauth2-boto-plugin.overridePythonAttrs (old: {
                    buildInputs = (old.buildInputs or [ ]) ++ [ super.setuptools ];
                  });
                  gsutil = super.gsutil.overridePythonAttrs (old: {
                    buildInputs = (old.buildInputs or [ ]) ++ [ super.setuptools ];
                  });
                  python-gflags = super.python-gflags.overridePythonAttrs (old: {
                    buildInputs = (old.buildInputs or [ ]) ++ [ super.setuptools ];
                  });
                });
              })
            ];
          };
        shell = with pkgs; shellWithPkgs [
          powerlifted
          parallel-full
          sqlite
        ];
      in
      {
        devShell = shell;
        defaultPackage = shell;
      });
}

And this is the error I get back when the compilation gets to bcrypt:

I tried multiple approaches - either having the shell not using poetry2nix and just call poetry shell (but then I get into weird libc++ linking issues) and trying to toggle preferWheels on and off. Nothing.

Do you have any pointers on how to make bcrypt / the python environment work? Thank you!
