title: "OpenSSL version is too old" while compiling http 2.4.16 on MacOS 10.11
body: <p>I encounter an error with OpenSSL while compiling http 2.4.16 on El Capitan 10.11.1.</p>
  
  <p>It is looking for OpenSSL version >= <strong>0.9.8a</strong>:</p>
  
  <pre><code>checking for OpenSSL... checking for user-provided OpenSSL base directory... none
  checking for OpenSSL version &gt;= 0.9.8a... FAILED
  configure: WARNING: OpenSSL version is too old
  </code></pre>
  
  <p>The default OpenSSL version is <strong>0.9.8zg</strong>:</p>
  
  <pre><code>$ openssl version
  OpenSSL 0.9.8zg 14 July 2015
  </code></pre>
  
  <p>And finally here is a part of my compilation line:</p>
  
  <pre><code>./configure --prefix=/usr/local/MyWebserver/httpd-2.4.12 \
  --enable-ssl \
  --with-few-things… \
  --disable-lots-of-things…
  </code></pre>
  
  <p>I don't want to install another openssl even with <code>brew</code>.</p>
