Fyi, there's a `cabal-install-head` package now[1] (may take a few minutes till its properly published in the PPA though); please test it and lemme know if it works as expected...

Thanks for uploading this. Nevertheless, GHC from head and cabal from head still don't like each other: https://travis-ci.org/haskell-opengl/StateVar/jobs/39470537#L103 I get "cabal: Prelude.chr: bad argument: 3031027"... o_O
