Excellent!

At first we'll need hscolour (sync just requested), because ghc6 needs it to 
build (afaict only the documentation needs this, otherwise, we'd be in severe 
bootstrapping trouble :/).

Next step is to merge ghc6 (I'm just trying a local build...).

Finally pretty much every haskell lib needs a rebuild, which it does in debian 
as well, so we can hopefully sync as much as possible. I used to have a list 
some time ago (with dependencies, because some libs need to be rebuilt in 
order), but I seem to have deleted it.

I guess 
	apt-cache rdepends ghc6 
should give at least a rough list of packages to look at.

Cheers,
    Stefan.
