Cabal doesn't play well with version constraints on the template-haskell package - it doesn't know it can't reinstall template-haskell.
The workaround is to figure out why QuickCheck has version constraints on template-haskell and solve that problem in the QuickCheck package a different way - perhaps with CPP conditonal compilation macros - and then remove the problematic version constraints.
