title: How to solve Insecure world writable dir /usr in PATH,mode 040777 warning on Ruby?
body: <p><code>/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/universal-darwin13/rbconfig.rb:213: warning: Insecure world writable dir /usr in PATH, mode 040777</code></p>
  
  <p>I've tried these two commands after searching for solutions on Stackexchange, but it didn't work for me. It still shows me the warning which I've pasted above.</p>
  
  <pre><code>sudo chmod 775 /usr/local
  
  sudo chmod go-w /usr/local/bin
  </code></pre>
  
  <p>How do I fix this warning message? I'm running OS X 10.9 Mavericks</p>
