[Haskell-cafe] How to eliminate Cabal warning message, re: internal library version number?

How do I eliminate these messages from my `cabal build` output? Warning: The package has an extraneous version range for a dependency on an internal library: {proj_name} >=0 && ==0.1.0.0. This version range includes the current package but isn't needed as the current package's library will always be used.
