title: How to downgrade to perl 5.10.1?
body: <p>I'm running into lots of issues with perl modules requiring <code>perl(:MODULE_COMPAT_5.10.1)</code>:</p>
  
  <pre><code>Error: Package: perl-Class-MOP-1.12-1.el6.x86_64 (epel)
             Requires: perl(:MODULE_COMPAT_5.10.1)
  Error: Package: perl-Moose-1.15-1.el6.x86_64 (epel)
             Requires: perl(:MODULE_COMPAT_5.10.1)
  </code></pre>
  
  <p>The installed perl version is 5.16.3, OS is Amazon Linux AMI release 2014.03, and I'd very much like to downgrade to perl 5.10.1 so that the compat issues are fixed. How do I do this?</p>
  
  <p>This happens in particular when I try to install perl-Net-Amazon-EC2, here's what <code>yum list shows</code>:</p>
  
  <p><code>perl-Net-Amazon-EC2.noarch 0.14-2.el6 epel</code></p>
  
  <p>So it's coming from epel and here's a corresponding section of repo file:</p>
  
  <pre><code>[epel]
  name=Extra Packages for Enterprise Linux 6 - $basearch
  #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
  mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&amp;arch=$basearch
  failovermethod=priority
  enabled=1
  gpgcheck=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
  </code></pre>
  
  <p>Seems like version in repo is 0.14 and the latest is 0.24 (I've tried installing it manually, but it did not work and I in any case don't want to install manually for all the packages)</p>
