Hello,

I've been trying to install `pandoc-crossref` on my Fedora 26 system using Cabal, but can't seem to do so. I've tried three different machines and get the same error on all. Would someone with some Haskell experience be able to help please?

Here's the error. I've also filed the upstream but they haven't been able to help either. It may be a Fedora specific issue?
