patch applied (packages/Cabal): Make die use an IOError that gets handled at the top level

  * Make die use an IOError that gets handled at the top level
  Rather than printing the error there and then and throwing an
  exit exception. The top handler now catches IOErrors and
  formats and prints them before throwing an exit exception.
  Fixes ticket #512.
