Many of the haskell packages including darcs, ghc, and well over 100 other packages (mostly libraries) are in the package manager ready to be installed.
The problem with Ubuntu (at least until the Feisty release a few days ago?) was that GHC wasn't up-to-date by default; it came with 6.4. Moving to 6.6 isn't a difficult feat (the generic binaries from the GHC site seem to work fine for Edgy, if you install libreadline too) but being behind that curve is noticeable. If you want to stay on the cutting edge Gentoo takes a lot of the hassle out of it, since you can use the repository stored on haskell.org. The downside is having to keep the rest of the system updated if you've got a slow machine. You pays your money, etc. D.
