title: CPython Build fails _ctypes and ssl
body: <p>I'm building CPython to use for building Pandas. </p>
  
  <p>I've forked, cloned and configured <code>CPython</code>. </p>
  
  <p>running <code>make -s -j2</code></p>
  
  <p>returns: <code>Python build finished successfully</code> along with some expected missing optional modules.</p>
  
  <p>but also includes</p>
  
  <pre><code>Could not build the ssl module!
  Python requires an OpenSSL 1.0.2 or 1.1 compatible with libssl with X509_VERIFY_PARAM_set1_host()
  </code></pre>
  
  <p>Is it ok to skip this module for the purposes of compiling Pandas? </p>
  
  <p>I tried</p>
  
  <pre><code>sudo apt-get install libssl-dev
  </code></pre>
  
  <p>and making again but got the same result. </p>
  
  <pre><code>dpkg -l | grep -i openssl
  </code></pre>
  
  <p>returns</p>
  
  <pre><code>ii openssl     1.1.0g-2ubuntu4.3
  </code></pre>
  
  <p>so maybe I just need to point OpenSSL at the newly installed LibreSSL?  </p>
  
  <p>Thanks for all suggestions</p>
