How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)

So where is this phantom node 0.6.1-pre version and how can I get rid of it? I'm trying to install libraries via NPM so that I can work on a project.

I tried using BREW to update before NVM, using "brew update" and "brew install node". I've tried deleting the "node" directory in my /usr/local/include and the "node" and "node_modules" in my "/usr/local/lib". I've tried uninstalling npm and reinstalling it following these instructions.

All of this because I was trying to update an older version of node to install the "zipstream" library. Now there's folders in my users directory, and the node version STILL isn't up to date, even though NVM says it's using 0.6.19.

Ideally, I'd like to uninstall nodejs, npm, and nvm, and just reinstall the entire thing from scratch on my system.
