  * Partial bugfix to allow traditional .cabal files without a library but
  global build dependencies.  The correct solution is to add global
  dependencies to each executable and implement dependency resolution
  for executables.
  
  The current workaround is to add the dependencies to the library, but
  disable building of the library.
