to be exact, problem is not downloading, but separating libraries from
the core package so they can be developed and updated independently.
fo example, you can update mtl from 2.0 to 3.0 version while using
still ghc 6.6 you installed four years ago. now library versions are
fixed at moment of major GHC release (6.4/6.6/..) and don't changed
during year or two
