[__6] fail (backjumping, conflict set: jsaddle, transformers, unliftio-core)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: jsaddle, servant, base, base-compat,
transformers, time, servant-lucid, miso, webkitgtk3-javascriptcore, stm,
unliftio-core
Try running with --minimize-conflict-set to improve the error message.
