If you're using GHC it comes with the standard Prelude and the modules in the base package, and perhaps a few other packages.

Most packages, like the split package (which contains the Data.List.Split module), aren't part of GHC itself. You'll have to import them as an explicit compilation step. This is easiest done with a build tool. Most Haskellers use either Cabal or Stack.

With Stack, for example, you can add the split package to your package.yaml file:

dependencies:
- base >= 4.7 && < 5
- split

You can also load an extra package when you use Stack to start GHCi. This is useful for ad-hoc experiments.
