title: issues with docker-compose up
body: <p>Whenever I am trying to run <code>docker-compose up</code> it shows the below error related to a version mismatch of client and server.</p>
  
  <pre><code>client and server don't have same version (client : 1.19, server: 1.18)
  </code></pre>
  
  <p>Below are the installed versions of docker-compose and docker itself. Neither docker, nor docker-compose have 1.19 and 1.18 versions. So actually this message is referring to which client and server?</p>
  
  <pre><code>[root@node1 composetest]# docker -v
  Docker version 1.6.2, build 7c8fca2/1.6.2
  [root@node1 composetest]# docker-compose up
  client and server don't have same version (client : 1.19, server: 1.18)
  </code></pre>
  
  <p>Further how to fix this issue. I am using centos 6 and  have upgraded the docker to latest version.I had installed docker-compose using pip.</p>
