title: Installing homebrew not possible under OS X 10.8.3
body: <p>I have installed the Xcode-Version 4.6.2 under OS X 10.8.3 and also the Command Line Tools. If I want to install homebrew with:</p>
  
  <pre><code>ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>/Users/MarcoMueller/.rbenv/shims/ruby: line 21: /usr/local/Cellar/rbenv/0.4.0/libexec/rbenv: No such file or directory
  </code></pre>
  
  <p>What could be the problem?</p>
  
  <p>Thank you</p>
