Hi Folks,

I have some trouble upgrading the homebrew formula to the latest.

Here is the PR reference,
https://github.com/Homebrew/homebrew-core/pull/59702

Error message is with Color package:

==> cabal v2-update
Config file path source is default config file.
Config file
/private/tmp/darcs-20200815-93928-lfe5vc/darcs-2.16.1/.brew_home/.cabal/config
not found.

cabal: color.hs doesn't exist



I was also trying to use Stack to do the installation in my local, running
into a similar build issue.

```
Error: While constructing the build plan, the following exceptions were
encountered:

In the dependencies for darcs-2.16.1:
    sandi must match >=0.4 && <0.6, but the stack configuration has no
specified version  (latest
          matching version is 0.5)
needed since darcs is a build target.

Some different approaches to resolving this:

  * Recommended action: try adding the following to your extra-deps
    in /Users/rchen/.stack/global-project/stack.yaml:

- sandi-0.5 at sha256
:b278d072ca717706ea38f9bd646e023f7f2576a778fb43565b434f93638849aa,3010

Plan construction failed.
```

Let me know I need to provide more information.

Thanks,
Rui
