If by "faulting in" you mean downloading and installing missing dependencies, then that's exactly what the cabal-install tool does.
This is exactly by "faulting in" .. an analogy ...
Installing cabal-install seems to be a chicken and egg problem if enough packages are not already installed ... if not enough then one (me) can die of a thousand paper cuts bootstrapping packages up to where cabal-install can be installed. I am running Ubuntu Linux. Cabl-install is written in Haskell? If so, is there a pre-compiled Cabal-install that I can just install with all dependencies (packages) including. I also want to install HaskellDB painlessly ;^) ??
In my experience, with recent GHC there are only 3 packages needed to install cabal-install and it's pretty painless. You need zlib, HTTP and something else that I can't recall off the top of my head (but it tells you). Each of these packages can be had from hackage and they are very standard cabal installations. Sometimes you also need to upgrade cabal; I don't think this was an issue with ghc 6.8.2 and newer though. Cabal-install is worth the pain. Once you have a recent cabal-install it becomes painless to try out new packages via Hackage. And we have some very cool packages there these days. I really need to get all my side projects there so people can play with them. </advocating> Jason
