Why is this a bug? Is there a reason why lens master should be expected to build with LTS 2.14?

Perhaps the implied suggestion is that stack should by default take packages from hackage if it helps with the build? The problem for stack is that the package index being up to date effects things. So stack is going to need some level of user intervention.

If there is a cabal.config file is is safe to take package from there.

Doing this is being tracked in #116

Closing in favor of #116
