title: NPM not creating .bin directory
body: <p>I'm using <em>npm v1.4.4</em> and <em>node v0.10.25</em> on <em>Mac OS X 10.9.2</em>.</p>
  
  <p>I've recently upgraded node and npm, and now <code>npm install</code> is no longer creating the .bin directory in node_modules.</p>
  
  <p>I've deleted node_modules, tried <code>npm install</code> again, but the directory and binaries are never created.</p>
  
  <p><em>Does anybody have any ideas as to why this is happening?</em></p>
  
  <p>Here is my <code>package.json</code>:</p>
