title: python bdist_rpm not using install_requires?
body: <p>I've created a new RPM using <code>python bdist_rpm</code> . Normally <code>python setup.py install</code> would install python dependencies like <code>websocket-client</code> or any other package. But the RPM just refuses to install anything.</p>
  
  <p>Apparently the suggestion from various other posts seem to be in the line of just requiring them in setup.cfg as rpm packages. This doesn't make sense to me since most of the rpm packages seem to be on really old version and I can't possibly create rpms for all the python packages i require. I need a much recent version and it doesn't make sense that the yum installs don't actually install the packages.</p>
  
  <p>What is the right (clean and easiest) way to do it ? I believe if a <code>setup.py</code> has something like </p>
  
  <pre><code>install_requires=[
      "validictory",
      "requests",
      "netlogger&gt;=4.3.0",
      "netifaces",
      "pyzmq",
      "psutil",
      "docopt"
  ],
  </code></pre>
  
  <p>Then it should try to either include them in the rpm or try to install it.
  I am trying on a clean centos vm using vagrant which I keep destroying and then install the rpm.</p>
