Where can I find MonadRandom or Control.Monad.Random to install? It doesn't seem to be a system library, I can't find it with cabal or Hoogle.
'cabal install MonadRandom' ought to work. Note that you may have to 'cabal update' first to make sure cabal has the most up-to-date package list. You can also always look at the complete list of packages on Hackage by going to hackage.haskell.org.

That worked.
I'm looking at this example from the docs. I understand most of this but I can't find a definition of getRandomR. See die has type (Rand g Int) I'm assuming getRandomR is a function that has that type, but I can't find its definition.
getRandomR has type (MonadRandom m, Random a) => (a, a) -> m a which in particular can be specialized to (RandomGen g) => (Int,Int) -> Rand g Int . The documentation for getRandomR, and the other methods of the MonadRandom class, can be found here: http://hackage.haskell.org/packages/archive/MonadRandom/0.1.3/doc/html/Contr... -Brent
