[Haskell-cafe] Hidden module?

Cabalising hsc2hc I get (this is actually from manually building the package): --- [paris@bagend hsc2hs-0.67.20061107]$ runghc Setup.hs build Preprocessing executables for hsc2hs-0.67.20061107... Building hsc2hs-0.67.20061107... Main.hs:32:7: Could not find module `System.Process': it is a member of package process-1.0.1.0, which is hidden [paris@bagend hsc2hs-0.67.20061107]$ which I cannot understand. Please help! --- Cristiano
