title: RHEL 6 - how to install 'GLIBC_2.14' or 'GLIBC_2.15'?
body: <p>I need these 2 packages installed on RHEL 6 linux system. 
  They are required by several other programs.</p>
  
  <p>When I do:</p>
  
  <pre><code>sudo yum install glibc-devel
  </code></pre>
  
  <p>this is output:</p>
  
  <pre><code>Loaded plugins: product-id, security
  Setting up Install Process
  Package glibc-devel-2.12-1.166.el6_7.1.x86_64 already installed and latest version
  Nothing to do
  </code></pre>
  
  <p>Is there some EPEL with GLIBC_2.15 for RHEL?
  If not - what is a workaround here?</p>
