[Haskell-beginners] Hackages that only depend on Haskell Platform

So after encountering the dangers associated with installing many random hackages I am on a mission to cull the herd. So to that effect: Is there a list of hackages available that *only* depend on the latest Haskell Platform? -or- Can such a list be reasonably generated? -or- Will there even be anything left after the hackages are filtered? Apologies if this is in fact already in the archives! Cheers, Darren
