If you're not using the cabal framework to build your program,

I thought I was.

you want to use "ghc --make" so it will chase down the package dependencies. Otherwise you would need to say "ghc -package mypretty".

Based on what I did to install the package, how am I supposed to use the package in a program? The book doesn't give any clue.
