Comment 7 for bug 70302

As long as GHC has no registerised-powerpc maintainer (which I believe is still true), and ghc bug #631 remains unfixed <http://hackage.haskell.org/trac/ghc/ticket/631> (even if it is fixed in GHC 6.8, that won't be out in time for Gutsy, but 6.8 will be in time for gutsy+1), I don't think this bug is going to be fixed. I think the best bet is to hope for #631 to be fixed soon, then let the Debian packagers turn on GHCi for the unregisterised architectures, and (if I understand the process correctly) Ubuntu can then inherit those changes from Debian as soon as practicable.

Although, I'm not sure how important "bootstrap issues with [(some particular)] older ghcs" are as time passes, in debian-ish environments, (and I'm not using ubuntu anymore either (for one thing, the two projects' release cycles and practices help Ubuntu be chronically behind by one on the newest GHC release...))
