I've been used to ghci not working on powerpc, and I revisisted this bug with the previous update to make sure it was tracked in Debian. To my surprise, the current version of ghci in testing, does in fact start and act like normal on my powerpc system. Below is the information collected by reportbug.
For my system, where previous late 6.* versions of ghc have had segfaults at startup for ghc --interactive, This version (below) 7.0.4 does work. $ ghci GHCi, version 7.0.4: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.
