body: <p>I'm trying to install the Now.js module for Node.js. It gets installed, but it doesn't work. When I install it, here's what I get:</p>
  
  <pre><code>eustace@eustace-desktop:/var/www/nowjs$ sudo npm install now -g
  
  &gt; node-proxy@0.5.1 install /usr/local/lib/node_modules/now/node_modules/node-proxy
  &gt; make

  <p>I'm trying to get the example working (http://nowjs.com/doc/example), but when I run helloworld_server.js in terminal, here's what I get:</p>

  <p>I'm using Node.js v0.4.11 and Ubuntu 11.04. I tried doing 'export NODE_PATH="/usr/local/lib/node"', but it didn't help.
  How do I fix this?</p>
