When building Hakyll using Stack as suggested, I do something like this (pinning the resolver version for immutability):
$ stack --resolver lts-6.6 install hakyll
But what I get is:
Progress: 10/23

I've tried various other lts-* resolvers but no luck there either, and can't really work out what's needed to fix the build issue... especially being a bit of a newbie here... Any ideas, please?
My guess is that you have corrupted packages in your ~/.stack.
So nuking ~/.stack and trying to install again would be a good check to see if that is the case.
