title: Tty.c: loadable library and perl binaries are mismatched
body: <p>I upgraded Ubuntu from zesty to bionic. In the process perl was upgraded from 5.24.1 to 5.26.1. Now I am getting this error when I try to install <code>Expect</code>.</p>
  
  <pre><code>Tty.c: loadable library and perl binaries are mismatched 
  </code></pre>
  
  <p>I have re-installed IO::Tty and that says it has installed correctly. There are other modules that are reporting similar errors.</p>
  
  <p>Here is the full output from the failed <code>Expect</code> install.</p>
