Build failure as seen on the stackage build server:

I'll try to see if I can reproduce it locally with the next stackage nightly snapshot.

Here's how I was able to reproduce locally:

$ stack unpack language-dockerfile-0.3.6.0 && cd language-dockerfile-0.3.6.0
$ vi stack.yaml # add the stack.yaml below
$ stack build

# stack.yaml
resolver: nightly-2017-12-09
extra-deps:
- ShellCheck-0.4.7
