Resolving dependencies...
Error: cabal: Could not resolve dependencies:

[__7] fail (backjumping, conflict set: chr-lang, chr-parse, containers)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: containers, base, deepseq, array,
chr-parse, unordered-containers, chr-lang, template-haskell, pretty
Try running with --minimize-conflict-set to improve the error message.
