title: Installing gevent on Centos error gcc
body: <p>I've installed all the requirements (I think) but I still get errors when running</p>
  
  <pre><code>pip install gevent
  </code></pre>
  
  <p>I've also tried installing from github with the same error below:</p>
  
  <pre><code>error: command 'gcc' failed with exit status 1
