[web-devel] Failed to compile authenticate

[Michael Snoyman]

Looks like you're running into a lot of the problems people have with
cabal fairly frequently. Your best bet is likely:

* Kill your .ghc folder (not necessarily required)
* cabal update
* cabal install yesod

That *should* solve it, let me know if you still have problems.
