I'm afraid I had to roll back the GHC version - its my work computer
and not being able to work on it turned out to be an issue...

Hmm, weird. It was giving constraints such as base-any && == 22.214.171.124,
which I assumed had come from hardcoding inside cabal. Given that
isn't the issue, my problem was probably elsewhere.

The computer I was working on had many different versions of GHC on,
each with different libraries. It's entirely possible something got
confusing and used the wrong ghc-pkg/ghc combination or some other
mess happened. I'd regard this as a hisen-bug, and if I get a chance
next week I'll do the same things again and see if the same things
