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.

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).

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

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.
