[Haskell-cafe] problem installing pivotal

I tried to install pivotal According to the site I must do: ghc --make Main -fglasgow-exts -package plugins I get cant satisfy package plugins I believe the more general problem is that one has to choose between 'direct' cabal installs and using debian's packages. At least this is the same situation Ive seen before in python, ruby etc. What do I do? So this is really 2 questions: 1. How to remove this error and install pivotal 2. Is it better to install haskell-platform or is it better to have a minimal install of ghc and then use hackage/cabal [Or is this a type- wrong question :-) ]
