Hi Phil, I hope your Haskell journey so far has been enjoyable. I'm rather new myself, but I'm pretty sure the answer to your question is:
By default, ghc doesn't try to include all the libraries that you import when you compile with "ghc test.hs". You can either specify these manually: "ghc test.hs -package hmatrix" or tell ghc to try and intelligently track down all the relevant packages with: "ghc --make test.hs". I hope that helps! -- Jason M.
