title: Which npm/bin folder(s) should be in the PATH ? ( OS X 10.8.2 / npm installed with homebrew )
body: <p>Upgrading <strong>node</strong> by using <strong>homebrew</strong> </p>
  
  <pre><code>==&gt; Downloading http://nodejs.org/dist/v0.8.21/node-v0.8.21.tar.gz

  ==&gt; ./configure --prefix=/usr/local/Cellar/node/0.8.21
  ==&gt; make install
  </code></pre>
  
  <p>I'm noticed this </p>
  
  <pre><code>==&gt; Caveats
  Homebrew installed npm.
  We recommend prepending the following path to your PATH environment
  variable to have npm-installed binaries picked up:
    /usr/local/share/npm/bin
  </code></pre>
  
  <p>In the <code>$PATH</code> I had already: <code>/usr/local/share/npm/lib/node_modules/scripted/bin</code>
  Should I add <code>/usr/local/share/npm/bin</code> too?</p>
  
  <p>Please note that <code>/usr/local/share/npm/bin</code> only contains two subfolder: <code>scr</code> and  <code>scripted</code> that are also in <code>/usr/local/share/npm/lib/node_modules/scripted/bin</code> so what's the <em>difference in the purpose</em> of these two folders?</p>
  
  <p><strong>EDIT</strong> 
  <code>/usr/local/share/npm/bin</code> only contains two symlinks ( not subfolders )</p>
