For me, Nix(OS) solved most of the problems: * Getting a dev env with `nix-shell -E '(import <nixpkgs> {}).somePackage'` where I can edit the source and compile it with the various `runPhase` commands[1]. Yes, a bit cumbersome, but it works and it is the same for all packages. * Integrating the resulting patch into the package manager using overrides[2]. Sure, applying the patch may break at some point, but I am more comfortable reviewing that by hand than rely on an agent that does it for me.
