title: Apache configure gives error invalid variable name: `with-ssl'
body: <p>I need Apache2.4 with ssl.</p>
  
  <p>AWS RHEL server I am using already has Apache2.2 and openssl 0.9 installed. I configured my Apache,apr,apr-util and pcre packages at /opt/products/apache2. everything is fine except the option</p>
  
  <pre><code>--enable-ssl
  </code></pre>
  
  <p>fails due to a dependency failure (openssl > 0.9.8a). No problem. I downloaded openssl 1.0.2a from open ssl and configured and installed it at /opt/openssl without problem.
  Now I need to configure Apache with </p>
  
  <pre><code>--enable-ssl --with-ssl=/opt/openssl
  </code></pre>
  
  <p>but the configure command returns the error</p>
  
  <blockquote>
    <p>"invalid variable name 'with-ssl'". </p>
  </blockquote>
  
  <p><code>configure -help</code> shows that with-ssl is an option.</p>
  
  <p>Is this a bug or something? I don't find any reference on the internet.</p>
