Comment (by duncan):

 I'm not sure there's a lot we can do in general. Certainly everything
 needs rebuilding when we install new ghc versions. When a minor release
 includes the same ghc version then it's safe to re-register existing ghc
 packages if and only if the ABIs match. We currently have no way of
 checking if the ABIs match (though we may do with GHC 6.12 and later).

 We can make rebuilding easier however. See
