Comment (by duncan):

 Yes, currently Cabal does not notice when the .cabal file has been updated
 without doing configure again. So cabal-setup build is not enough, you
 have to cabal-setup configure && cabal-setup build. I'd like to include
 this feature in the Cabal dependency analysis project, ie it should
 automatically rebuild the appropriate things depending on what has been
 changed in the .cabal file.

 As for Cabal doing dependency analysis for packages, it does not need to
 be as accurate as ghc, so long as it is conservatively inaccurate. Then
 it'll invoke ghc which might decide that there's nothing to do afterall.
