title: Modifying /private/etc/paths did not change $PATH after a reboot
body: <p>On a rMBP here. I'm not sure what the script is that is responsible for doing this. Basically I want to add the path to python utils to the <code>$PATH</code>... </p>
  
  <p>For example, I brewed python <code>brew python</code> in order to get <code>pip</code>, then ran <code>pip install flake8</code>. Now </p>
  
  <pre><code>$ which flake8
  flake8 not found
  
  $ find / | grep flake8
  ...
  ......
  /usr/local/share/python/flake8
  
  $ ls -la /usr/local/share/python/
  total 32

  </code></pre>
  
  <p>Alright! </p>
  
  <pre><code>$ cat /private/etc/paths
  /usr/bin
  /bin
  /usr/sbin
  /sbin
  /usr/local/bin
  
  $ sudo vim /private/etc/paths
  $ cat /private/etc/paths
  /usr/bin
  /bin
  /usr/sbin
  /sbin
  /usr/local/bin
  /usr/local/share/python
  </code></pre>
  
  <p>Make a new shell, check <code>$PATH</code>, python not there. Okay. </p>
  
  <p>Reboot, start a new shell, check <code>$PATH</code>, python <strong>still</strong> not there. </p>
  
  <p>Oh, by the way, the solution is <strong>not</strong> to append, with anything like <code>export PATH=$PATH:newpath</code>, because I don't actually care to run <code>flake8</code> from the command-line, I want Sublime Text 3' SublimeLinter plugin to actually know where it is without putting some hacky config in the settings for the editor. </p>
