title: sudo: ./install.sh: command not found is not working on Lion
body: <p>I've been following this tutorial in order to get SimpleOpenNI installed on my mac but I keep getting stuck at installing the OpenNI and NITE components because it requires me to navigate to the folders in Terminal and then run "sudo ./install.sh". I do this and I get this error:</p>
  
  <p>sudo: ./install.sh: command not found</p>
  
  <p>I've installed Command Line Tools in Xcode and everything.</p>
  
  <p>Thanks</p>
