 Cabal should be able to reinstall all dependencies of a package easily.

 Steps to Reproduce:
 1. Break your cabal install somehow, keeping the database of the installed
 packages. For example remove the ~/.cabal folder.
 2. Try to install a program with a dependency that you installed before
 via cabal (and resided in ~/.cabal)
 3. Get error message about missing files/broken package.
 4. Try to reinstall the dependencies of the program you want to reinstall:
 cabal install foo --reinstall --only-dependencies

 Expected results:
 all dependencies of foo is reinstalled.

 Actual result:
 Resolving dependencies...
 No packages to be installed. All the requested packages are already
 installed.
 If you want to reinstall anyway then use the --reinstall flag.
