[Haskell-cafe] Haddock Secrets?

Hey everyone, Is there some secret to getting Haddock to work with literate Haskell sources that I am missing? For example, when I download Takusen and type cabal configure cabal haddock It produces HTML files complete with a table of contents, but with all of the documentation stripped out. Oddly, I know that it is *possible* to process the literate sources into documentation because it appears on Hackage! I am doing this on OSX Snow Leopard with GHC 6.10.4 and Haddock 2.5. Thanks, Greg
