perhaps you're missing mtl. (There are also C.M.Trans.State in transformers, though IIRC you have to use lift there to access the methods in your monad stack.)

From the homework description I've tried running:

dlee@morty ~/repos/cis194/week7 $ runhaskell StringBufEditor.hs

Editor.hs:11:8:
    Could not find module `Control.Monad.State'
    Perhaps you meant
      Control.Monad.ST (from base)
      Control.Monad.ST.Safe (from base)
      Control.Monad.Fix (from base)
    Use -v to see a list of the files searched for.

Is my haskell install messed up?   Have the libraries changed since the homework was created?

Thanks,

dustin
