procmail fails to build in a funny way

In reply to @SeTSeR:matrix.org
Hello! How can I override Python package `watchdog` from within overlay? I tried this:
```nix
python3Packages = super.python3Packages.overrideScope (self: super: {
  watchdog = super.watchdog.overrideAttrs (self: super: {
    doCheck = false;
  }
 });
```
However, `nix why-depends` still shows that dependency on old `watchdog` is still in place. It shows that `werkzeug` depends on this library. In Nixpkgs I found, that `werkzeug` has `watchdog` in `nativeBuildInputs`. However, neither putting `watchdog` override in `buildPackages` nor removing the library from `nativeBuildInputs` didn’t do a trick. What else could I try?

In reply to @alex:tunstall.xyz
It might be coming from one of the other Python package sets. Maybe look at the definition of python3Packages in Nixpkgs, because I suspect that it's actually an alias for one of the other sets.

In reply to @SeTSeR:matrix.org
It’s strange, because I had to disable tests for some other packages and such override did the trick for them. But now I see the problem more clearly: werkzeug sees the updated watchdog, but for some reason this updated watchdog still runs tests.
