title: Error when starting rails server: warning: Insecure world writable dir /usr in PATH, mode 040777
body: <p>I'm following the Ruby tutorial on Treehouse and I keep getting the following error when starting the rails server:</p>
  
  <pre><code>/usr/local/rvm/gems/ruby-1.9.3-p392@global/gems/bundler-1.2.4/lib/bundler/runtime.rb:197: warning: Insecure world writable dir /usr in PATH, mode 040777
  /usr/local/rvm/gems/ruby-1.9.3-p392@global/gems/bundler-1.2.4/lib/bundler/runtime.rb:197: warning: Insecure world writable dir /usr in PATH, mode 040777
  </code></pre>
  
  <p>I tried fixing it with the 
      sudo chmod o-w /usr/local/ 
  fix and other variations, but sadly that didn't do anything for me.</p>
  
  <p>Even with that error though the server would still start and everything would work fine but now I get a lot of other errors as well and the server won't even start anymore, and I thought they might be connected somehow? </p>
  
  <p>This is the error I get now:</p>

  <p>Any suggestions on fixing this? I tried reinstalling Rails but that didn't help, still the same errors.</p>
  
  <p>Thanks!</p>
