title: Cannot find node-gyp
body: <p>I installed node v0.8.22 with homebrew. I have my node binary in <code>/usr/local/bin/</code> but I need to recompile a node add-on with <code>node-gyp</code> but it cannot seem to find it in my <code>PATH</code>. I tried running <code>npm install -g node-gyp</code> but it's still not in my path.</p>
  
  <p>I noticed that npm -g installs everything into <code>/usr/local/share/npm/bin/</code>. Does this mean I need to add this to my <code>PATH</code>?</p>
