'cabal update' followed by 'cabal install pandoc-include' fails to build

[marekkowalczyk]

I've tried several times over a couple of days to the same effect:

error.txt

macOS 10.14 (18A391)

Any ideas how to fix this?

I confirm that in macOS 10.13.6 today, after cabal update.

Doesn't work:

It's a bit heavy-weight, but I do this sort of thing now via the pandocs API and classes, which is a joy but there are quirks. http://hackage.haskell.org/package/readme-lhs is an example.
