Here is the error message cabal and ghc reported:
[13 of 15] Compiling Test.QuickCheck.All ( Test/QuickCheck/All.hs, dist/dist-sandbox-e58b37f7/build/Test/QuickCheck/All.o )

Test/QuickCheck/All.hs:91:11:
    Constructor ‘ClassOpI’ should have 3 arguments, but has been given 4
    In the pattern: ClassOpI _ ty _ _
    In an equation for ‘infoType’: infoType (ClassOpI _ ty _ _) = ty

I changed my project's dependency on QuickCheck-2.8.1 and it builds
correctly.
