package haskell-src depending on happy?

[Andreas Marth]

Hi!

I just tried to install haskell-src with cabal and passed 'runhaskell
setup.hs configure' but 'runhaskell setup.hs build' died with
"Language\Haskell\Parser.ly: no happy preprocessor available".
This looks to me like happy is required for haskell-src, but it is not
mentenied in the dependencies.

Do I really have to install happy? (In the past that was a nightmare if I
remember correctly.)
My system is Win2k and ghc-6.1.1.

Kind regards
Andreas
