Currently (2009-08-02) GHC 6.10.4 and a few libraries are hard masked, meaning you will have to p.unmask yourself before installing. This is because we're still updating the portage packages to get full GHC 6.10.4 support.

As of this writing the Gentoo ebuilds for Haskell Platform are no longer hard masked, which means unmasking them is no longer needed. However, 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

Gentoo supports the Haskell Platform!

1 Masking and Unmasking

As of this writing the Gentoo ebuilds for Haskell Platform are no longer hard masked, which means unmasking them is no longer needed. However, 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

dev-haskell/haskell-platform  
dev-haskell/fgl  
dev-haskell/haskell-src
dev-haskell/html
dev-haskell/network
dev-haskell/zlib
dev-haskell/mtl
dev-haskell/cabal-install
dev-haskell/stm
dev-haskell/parsec
dev-haskell/regex-posix
dev-haskell/happy
dev-haskell/xhtml
dev-haskell/editline
dev-haskell/cgi
dev-haskell/parallel
dev-haskell/time
dev-haskell/quickcheck
dev-lang/ghc
dev-haskell/glut
dev-haskell/http
dev-haskell/regex-base
app-admin/haskell-updater
dev-haskell/haddock

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

=dev-lang/ghc-6.12.3
=app-admin/haskell-updater-1.1.3.0
=dev-haskell/stm-2.1.2.2
=dev-haskell/haddock-2.6.1

2 Install

Now, to install, run:

emerge haskell-platform

This will pull the GHC compiler, Cabal, and all the libraries included in HP. If you want haddock documentation, set your USE="doc". If you also want profiling libraries, set USE="profile".
