title: Error: Module did not self-register
body: <p>Have tried all the documented fixes I could find: <code>npm update</code>, <code>npm rebuild</code>, manually removed node_modules folder as well as <code>rm -r node_modules</code> then <code>npm install</code> or <code>meteor npm install --save bcrypt</code>, and <code>curl https://install.meteor.com/ | sh</code>. Still getting:</p>
  
  <pre><code>20160927-14:57:19.627(-7)? [Error: Module did not self-register.]
  W20160927-14:57:20.974(-7)? (STDERR) js-bson: Failed to load c++ bson extension, using pure JS version
  </code></pre>
  
  <p>Node 4.5.0 / meteor 1.4.1.1 / mac os 10.11.6</p>
  
  <p>Any other ideas greatly appreciated. Thanks</p>
