title: Installing Archive::ZIp Perl package with cpan on centos7 fails with "not in gzip format"
body: <p>I have a CentOS 7 VM.  I installed "cpan-CPAN" from yum.  I ran "cpan" and let it configure itself.  I ran it with sudo, although I realized later I didn't necessarily have to do that, if I later selected the "sudo" installation mode.</p>
  
  <p>After it finished configuring, I entered "install Archive::Zip".  It gave me this:</p>
