title: chown illegal group name (mac os x)
body: <p>I'm trying to run the following command in Terminal: </p>
  
  <pre><code>chown -R couchdb:couchdb /usr/local/var/log/couchdb
  </code></pre>
  
  <p>However, I keep getting this message:</p>
  
  <pre><code>chown: couchdb: illegal group name
  </code></pre>
  
  <p>I am using mac osx (mountain lion) and I have command line tools installed. I really don't know very much about unix, but I've been googling the illegal group name error and haven't turned up anything that would help. What am I overlooking? Any additional resources you think might be helpful also appreciated.</p>
