[Haskell-cafe] Problem building the plugins package

Hello I am having troubles building the plugins package : manu:~/Desktop/tmp manu$ cabal install plugins Resolving dependencies... cabal: cannot configure plugins-1.2. It requires ghc >=6.8 There is no available version of ghc that satisfies >=6.8 I am on a Mac PPC (OS X 10.4) with ghc-6.8.2 and Cabal-1.4.0.1 so the error message is puzzling... Can anyone help ? I'd like to install Lambdabot and plugins is one of the dependencies... Thanks Manu
