 Cabal doesn't complain if the build depends on a Haskell module that
 exists in the filesystem properly, but is not mentioned in the cabal file
 itself as part of "exposed-modules" or "other-modules". The build succeeds
 because ghc can find the relevant file just fine.

 I've got bitten by this several times, especially after pushing a package
 to hackage, only to get it fail to build on the server because I've failed
 to put the name of a file in the appropriate section of the cabal file,
 thus it didn't make it to the .tar.gz bundle that got uploaded to the
 server.

 I realize this might be hard to ensure, as it would require a deeper look
 into the dependencies between modules, but I trust the GHC API should have
 all the information necessary for cabal to complain appropriately.
