[Haskell-cafe] Building "plugins" from Hackage

Hello List, when I try to install the package "plugins" with cabal i get the following error. cabal: dependencies conflict: ghc-6.8.3 requires Cabal ==1.2.4.0 however Cabal-1.2.4.0 was excluded because plugins-1.3.1 requires Cabal ==1.4.* Is there a way to resolve this? Any ideas? Sol.
