dev-haskell/haskell-platform has a ~amd64 flag. Maybe it can be removed now.

Thanks for showing your interest in the haskell platform and the haskell toolchain on gentoo! However, the haskell platform is p.masked on gentoo, masked for testing. Before we dare to p.unmask it, we want to test it properly, mostly due to that it brings a new ghc version, 6.10.4, the first version from 6.10.x we'll have in portage. Currently I'm aware that we need to fix these packages * gtk2hs * hdbc in portage before ghc 6.10.4 will work with them. Possibly there are more packages, help me find them! Once it's p.unmasked, we need to fix all 28 packages the haskell-platform depends on, to also have the ~amd64 flag removed. So yes, we're heading that way, but it includes several steps and it'll take time. You're welcome to visit irc channel #gentoo-haskell on the freenode network, where we co-ordinate our efforts.
