Issue with pdfstudio2024 Installation

Unable to reference locally installed golang flake executable like "{$pkgs.todocalmenu}/bin/todocalmenu"

I would strongly recommend against this, as this is essentially creating a broken overlay, where if you try overlay some packages which happen to be dependencies of todocalmenu, it will not actually overlay those dependencies, due to todocalmenu using a different nixpkgs instance. Ideally the todocalmenu flake should expose its own overlay where it uses final.callPackage, and consumers of that overlay would in turn be able to incorporate the package into their current nixpkgs instance more effe…
