title: Python build Error : Failed to build these modules: _ssl
body: <p>I want to install python 2.7.13 in my working OS. The OS is following:</p>
  <blockquote>
  <p>Linux XXX-centos-01 2.6.32-696.el6.x86_64 #1 SMP Tue Mar 21 19:29:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux</p>
  </blockquote>
  <p>I download python source and compile with the following step:</p>
  <blockquote>
  <p>Step1</p>
  <blockquote>
  <p>./configure --prefix=/usr/local/lib/python2.7.13 --enable-ipv6</p>
  </blockquote>
  <p>Step2</p>
  <blockquote>
  <p>make</p>
  </blockquote>
  </blockquote>
  <p>No Error but fail to build __ssl :</p>
  <blockquote>
  <p>Python build finished, but the necessary bits to build these modules were not found:</p>
  <p>_tkinter           bsddb185           dl
  imageop            sunaudiodev</p>
  <p>To find the necessary bits, look in setup.py in detect_modules() for the module's name.</p>
  <p>Failed to build these modules:</p>
  <p>_ssl</p>
  </blockquote>
  <p>But the openssl module i have installed.</p>
  <blockquote>
  <p>[root@lhkvm77-centos-01 Python-2.7.13]# rpm -aq|grep openssl</p>
  <p>openssl-1.0.1e-57.el6.x86_64</p>
  <p>openssl-devel-1.0.1e-57.el6.x86_64</p>
