Good, we're almost there! I strongly suspect it is a base constraint. Go in your something.cabal file, build-depends section(s) and modify it from: base >= 4.somenumber && < 4.10 to base >= 4.somenumber && < 4.11 And try cabal new-build again. If that fails, please include the content of your `build-depends:` portion in your message -F
