Removing the --constraint="utf8-string==0.3.8" does not solve the issue...

The problem is that the dependencies are not satisfied. It seems you have an old GHC 7.6.3 since you have the package base-4.6.0.1. This is indicated in line

rejecting: base-4.6.0.1/installed-6c3... (conflict: clafer => base>=4.7.0.1 &&
<5)

We only track the latest releases of GHC (which have base>=4.7.0.1). See requirements.

Execute ghc --version and cabal --version to see the installed versions.

On Mac, you can use Haskell Platform 2014.2.0.0 for Mac OS X, 64bit. Alternatively, you can also use GHC7.8.4 - I have not tried that one yet but it should work just as well as the platform (except that you have to manually execute cabal install alex happy because they come included in the platform).
