Haskell Platform
The Haskell Platform is a blessed library and tool suite for Haskell distilled from Hackage, along with installers for a wide variety of systems.
IOW, It's Haskell with Batteries Included.
ghc on jaunty is totally out of date. I recommend you grab the latest bin from the ghc official site. After that, just install Haskell Platform. It contains a variety of selected commonly useful lib and tools. You just dont need to install (and set up) 'em one by one.
Just a note for jaunty: install libedit-dev (not libeditline-dev) if you got a dep error for editline.
