Comment (by duncan):

 It's been pointed out that this is the natural thing to suggest to users
 when `cabal configure` fails with missing dependencies.

 The alternative is to tell users to do something like:

 {{{
 $ cabal configure
 Resolving dependencies...
 Configuring foo-1.0...
 setup: At least the following dependencies are missing:
 bar >= 1.0
 cabal: You can install these dependencies with:
   cabal install 'bar >= 1.0'
 }}}

 It would have to give the version constraints appropriately and in quotes
 to prevent bad things with the shell.
