You're using ghc-8.0.2... > Using compiler: ghc-8.0.2 which should have base-4.9.x.y... > Dependency base >=4.8 && <5: using base-4.9.1.0 Okay. And base-4.9.1.0 has the "Semigroup" class in Data.Semigroup with <> as its binary operation: http://hackage.haskell.org/package/base-4.9.1.0/docs/Data-Semigroup.html And yet, the build is complaining about that very thing being missing: > src/OptionalConfiguration.hs:68:8: error: > ‘<>’ is not a (visible) method of class ‘Semigroup’ Beats me. Time to ask for help.

This new version contains a one-line upstream fix to unbreak the build on ghc-8.0 and ghc-8.2 (but not higher or lower versions...). Poor Toralf.

Sorry toralf, I actually could have tested this one since I have ghc-8.0.2 on the server that runs this.
