Towerjs locales error

I am experimenting with towerjs. I just followed the instructions to create a project.

npm install tower -g
npm install grunt -g
mongod
tower new app
cd app
npm install

And when I try to start the server for the project I get the following error:

GT@ubuntu:~/work/app$ node server.js 

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^

Any help would be appreciated.

Thanks

UPDATE:

With further investigation

_path = require('path')    
_path.sep

seems to return undefined. Why would it not return /?

Hey so the problem was that I had to update node to the latest version (v0.8.8). My bad.
