title: force module install with CPAN
body: <p>I know it's easy to install a module with 'force' using CPAN from command prompt. I am trying to achieve same through the script:</p>
  
  <pre><code>use CPAN;
  eval "use Filesys::DiskSpace" or do {
      CPAN::install("Filesys::DiskSpace");
  };
  </code></pre>
  
  <p>Is there any way to add the option 'force' to the code?
  I am having the following error while compiling the module:</p>
  
  <pre><code>  make test had returned bad status, won't install without force
  </code></pre>
  
  <p>The warnings could not be serious, so I would like to proceed with the installation.
  Thanks.</p>
