You probably need to install alex and happy. Cabal doesn't
automatically install them, since they are executables used at compile
time and not libraries. Try:
cabal install alex happy
cabal install yesod
Let us know if you still have problems.

On OSX 10.6.6 I'm trying to install Yesod through Cabal but it fails because its unable to build cryptocipher. Has anyone seen this or know an answer?
