Hello, I am a budding Common Lisper. I was working on a <a href="https://github.com/joachifm/cl-mechanize">cl-mechanize</a> script to fill out an HTML form when I noticed that one of cl-mechanize&#39;s dependencies, <a href="http://common-lisp.net/project/cl-plus-ssl/">cl+ssl</a>, depends on CFFI.<div>

<br></div><div>When I try to load cl-mechanize, which loads drakma, which loads cl+ssl, I get the following message:<div><br></div><div><font class="Apple-style-span" face="&#39;courier new&#39;, monospace">*** - CFFI requires CLISP compiled with dynamic FFI support.</font></div>

<div><br></div><div>The problem seems to be that ffcall is not installed. When I try to install it with MacPorts, I get this message:</div><div><br></div><div><div><font class="Apple-style-span" face="&#39;courier new&#39;, monospace">$ sudo port install ffcall</font></div>
