extensible-exceptions configuration failure, ghc 6.8.1, cabal 1.2.2.0

Hi, extensible-exceptions-0.1.1.0 # runghc Setup.hs configure Setup.hs: extensible-exceptions.cabal:21: Parse of field 'extensions' failed: It builds fine after upgrading cabal to 1.6; probably the correct dependency on cabal version is somewhere in between 1.2 and 1.6 Thanks, --A
