Dependency Issue with "cabal install"

[alexandroid000]

Hi,

Ran into a dependency issue when installing with "cabal install". Output is below. I am on Arch Linux. After running into this issue I installed with stack and that worked fine, but figured I'd document this anyway. Also, might want to update the wiki to point people toward stack?

Thanks for developing this project btw, I'm really excited about it.

Thanks for the report! The wiki change is easy. For the actual problem, we could put an upper bound on base to prevent a newer GHC from breaking things, or we can do the right thing and update everything. I vote we do the right thing 😛

I updated the wiki.
