title: tensorflow requesting GLIBC 2.14 despite machine running 2.19
body: <p>I've seen many posts about installing tensorflow without having to update GLIBC 2.12. I didn't have that constraint so I got GLIBC 2.19 on a GCC 4.4.7 20120313 (Red Hat 4.4.7-1) linux cluster: </p>
  
  <pre><code>ldd --version
  ldd (GNU libc) 2.19
  </code></pre>
  
  <p>I have a Python 3.4.5 virtual environment to which I've pip installed tensorflow 0.11.0 via:</p>
  
  <pre><code>export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.11.0-cp34-cp34m-linux_x86_64.whl
  
  pip3 install --ignore-installed --upgrade $TF_BINARY_URL
  </code></pre>
  
  <p>I do the following and observe:</p>
  
  <pre><code>python
  import tensorflow

  <p>My understanding is that there is backwards compatibility with the absent 2.14 so a downgrade to it doesn't seem like the next best step and would probably anger the admin. Are there better things to try?  </p>
