You should not package ghc-array, ghc-containers, or ghc-binary — these are all provided by GHC itself. It is possible that there are some more packages for which this applies (possibly including semigroupoids). The next thing you should check is that you’re packaging only those versions of Haskell packages that are part of LTSHaskell or Stackage. Do not package the latest versions. -- Ricardo
