Did you re-run configure after changing the cabal file? Also, what ghc-pkg says has absolutely nothing to do with this; the options Cabal passes completely override the ghc-pkg exposure flags.I can hardly fault you for not knowing the answer to a Cabal FAQ, since Cabal doesn't actually have a FAQ list yet. You are running into the same problem as http://www.haskell.org/pipermail/haskell-cafe/2007-August/030276.html, and most of my explanation there applies here. Stefan
