title: Cannot import any modules (installed used pip) in python 2.7.14
body: <p>I downloaded the source code of python 2.7.14 and built it and installed it on linux ( Red Hat 4.8.5-16 ). I have earlier installed <code>python-magic</code> and <code>requests</code> libraries. Now when I try to import modules installed using <code>pip</code>, I get this:</p>
  
  <pre><code>$ python2
  Python 2.7.14 (default, Nov  9 2017, 09:05:45) 
  [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import magic
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named magic
  &gt;&gt;&gt; import requests
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named requests
  </code></pre>
  
  <p>while similar thing works perfectly fine in python 2.7.5 (default with the RHEL system)</p>
  
  <pre><code>$ python
  Python 2.7.5 (default, May  3 2017, 07:55:04) 
  [GCC 4.8.5 20150623 (Red Hat 4.8.5-14)] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import magic
  &gt;&gt;&gt; import requests
  &gt;&gt;&gt; 
  </code></pre>
  
  <p>Am I missing any configuration step here?</p>
