 subject="Reproduction of bug with "pure" stack build"

I am able to reproduce this bug with an entirely local stack build (i.e., no global haskell installs) on arch linux. To make sure I began with a clean build, I removed local directories (rm -r ~/.ghc, rm -r ~/.stack, rm -r ~/.cabal) and then uninstalled all arch linux haskell packages (including ghc and ghc-libs). I downloaded the standalone stack and then ran stack clean, stack setup, stack install in a cloned git-annex repo.
