Error: cycle detected (using M1)

Hi all,
So I run through the step by step guide:

1. Called `nix-build -A project`
2. Called `nix-shell default.nix -A shell`

In step 2 it looks like it start to download dependencies and then stop with following error:

```
stripping (with command strip and flags -S) in /nix/store/z46frksw53sm6rcmzk776badybkdm3jv-ghcid-0.8.7-bin/bin
patching script interpreter paths in /nix/store/z46frksw53sm6rcmzk776badybkdm3jv-ghcid-0.8.7-bin
error: cycle detected in build of '/nix/store/fwpl9v7aarnxgk581k32hcq3il4n6h54-ghcid-0.8.7.drv' in the references of output 'bin' from output 'out'
```

Reproduce the failure with `nix-build -A project` followed by `nix-shell default.nix -A shell`. Start by inspecting `default.nix` and the `ghcid-0.8.7` dependency build references; done means the shell builds without the reported cycle-detected error.
