Which version of GHC are you using?  If you're using 6.12, then you're out of luck: plugins won't work with it yet. ?? Is 6.12 too young or too old??

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.

Preferably, use a distro package if there is one.  If there isn't, then use cabal-install to install it to your home directory (which means you'll have to maintain it yourself).

So this is really 2 questions: 1. How to remove this error and install pivotal

cabal install pivotal (if you have GHC-6.10.*)

I am not sure how to resolve this: use cabal install and 'preferably use a distro' In any case with cabal install pivotal I get cabal: There is no package named pivotal. Perhaps you need to run 'cabal update' first? (this was just after a cabal update) Finally: Is it better to take up these (kind of) questions on the ghc list rather than here?

...

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 :-) ]

In general, I recommend you stick with your distribution's packages as much as possible (assuming they're kept up to date) and only resort to cabal-install when necessary; distribution packages typically interact with the system (in terms of non-Haskell dependencies, etc.) better.
