Can't find parsec

[Colin Paul Adams]

I am trying to incorporate Dana Xu's static contract checking code
into ghc 6.11. I've run into a problem that puzzles me. I am getting
the following error message:


verify/SimplIface.lhs:16:7:
    Could not find module `Text.ParserCombinators.Parsec.Language':
      Use -v to see a list of the files searched for.


But a quick find command shows that

./utils/ext-core/Language/Core/ParsecParser.hs

has this very same import, so I figure it must be usable within the
compiler.
What do I have to do to get it to find this module?
