title: Mac os permissions prevent me to delete files
body: <p>I installed easy_install on mac wityh the following command:</p>
  
  <pre><code>curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python
  </code></pre>
  
  <p>After that I tried to install pip but couldn't.
  After checking here is what I have in /usr/bin</p>
  
  <pre><code>$ ls -l easy*
  -rwxr-xr-x  2 root  wheel  925  7 Jan  2016 easy_install
  -rwxr-xr-x  1 root  wheel  454  7 Jan  2016 easy_install-2.6
  -rwxr-xr-x  1 root  wheel  461  7 Jan  2016 easy_install-2.7
  </code></pre>
  
  <p>Probably it does not work because I have 2 versions installed now. I am in the list of sudoers but even with sudo I cannot delete these files:</p>
  
  <pre><code>sudo rm -f easy_install-2.6
  Password:
  rm: easy_install-2.6: Operation not permitted
  </code></pre>
  
  <p>When I log in to this macbook there is my username and also Administrator which I do not have access to now.</p>
  
  <p>Is there a way to be able to delete these files without having to wait until the person that has the password for Administrator comes back from vacation?</p>
  
  <p>Here is my macbook info</p>
  
  <pre><code>  System Version: OS X 10.11.6 (15G31)
    Kernel Version: Darwin 15.6.0
    Boot Volume: Macintosh HD
  </code></pre>
  
  <p>Thanks</p>
