title: error when importing ijson module python
body: <p>I need to parse some large (2 Gb+) files into python. I have tried it with the json module but I get a memory error as its methods all load the files at once. 
  I then moved on into installing ijson which suposedly implements a iterator-based way of parsing the file. However when I run:</p>
  
  <p>import ijson</p>
  
  <p>I get exception : YAJL shared object not found.</p>
  
  <p>Has anyone found a similar issue?
  any help would be greatly appreciated</p>
  
  <p>Regards</p>
