[Haskell-beginners] How to get HLint working?

Hello, I'm trying to install HLint but I can't figure out how to use it. It seems like the install works, but when I type "hlint file.hs" my terminal gives an error. Here's a copy of my terminal output: http://pastebin.com/n071J2mL It looks like the install works, but at the end you can see that it doesn't function as I am expecting. I'm having difficulty finding relevant documentation. Help please? Avery
