Issue installing Snap on macOS Sierra

Question

I\'m having trouble installing the Haskell framework Snap on macOS Sierra. Whenever I install it, I get the following message:

Resolving dependencies...

There was an issue with full 8.2.1 binary platform builds that's just been resolved: https://mail.haskell.org/pipermail/haskell-cafe/2017-October/127979.html

This was likely an instance of that.
