Gentoo supports the Haskell Platform!
There are two ways to install haskell-platform, from the main portage tree or the overlay. The version in portage isn't the latest, so some work must be done to set this up. To use the overlay, we just need to add it. The overlay is recommended.
To get the latest version use the overlay. If you haven't already, install layman (this is used to setup overlays). Then run 'layman -a haskell' to install the haskell overlay. Now you are ready to install.
1.2 Portage Setup
To use the version in the portage tree, some work must be done. On 64 bit systems the ebuilds is not stable yet, so they need to be enabled by adding these entries to /etc/portage/package.keywords

Furthermore, because the ebuild for haskell-platform (dev-haskell/haskell-platform-2009.2.0.2) uses the old version of ghc (dev-lang/ghc-6.10.4), it will conflict with newer ebuilds that use newer versions such as ghc-6.12.3. In order to resolve this conflict the newer ebuilds that uses ghc-6.12.3 need to be masked by adding these entries to /etc/portage/package.mask

Now, to install, run:
This will pull the GHC compiler, Cabal, and all the libraries included in HP. If you want haddock documentation, set your
