Failing to deploy nextjs app with sharp / node-canvas

Question

Im trying to use Nixpacks to pre-install some python deps that `node-canvas` requires:

```
NIXPACKS_PKGS="python313 pkg-config cairo pango libpng giflib librsvg pixman"
```

But Im getting the following error:

```
Package pixman-1 was not found in the pkg-config search path.
```

Has anyone successfuly deployed a next.js app with sharp installed? I keep getting diferent errors with node-gyp (with this being the last one that I couldnt figure out how to fix)
