  ## Until IHaskell goes on a bigger diet, we need this nonsense
  ## A clean build gets timed out by travis
  ## So for now we install a few packages and fail the build in a way that the cache gets committed
  ## This means each new item in the build matrix _will_ fail on first build.
  ## Note on osx, the cache is so big, and the bandwidth so limited, that the cache upload process gets timed out.
