 Currently, cabal tries all possible flag assignments to fulfill the
 requirements on Haskell packages. For Gtk2Hs and probably other wrappers
 around C libraries it would be great to extend this functionality to pkg-
 config dependencies. They follow very similar convention when it comes to
 versioning but currently the users of my Setup.hs script need to specify
 the right flag combination to make configuring succeed.
