Since 6.8 iirc, GHC no longer comes with parsec, you have to install the package yourself if you want to use it,

cabal install parsec

This does not seem to be needed. import Text.ParserCombinators.Parsec seems fine.

also mtl is no longer one of the libraries that come with GHC,

cabal install mtl

What is mtl ? Thanks, Aaron

HTH, Daniel
