title: No module _cffi_ freezing with cx_Freeze
body: <p>I am developing a PySide application (Qt for Python) and I would like to freeze it using cx_Freeze.</p>
  
  <p>When I run <code>python setup.py build</code> using my setup file below, it creates the build directory without errors, but then when I run the .exe file generated, I get the error message shown below:</p>
  
  <pre><code>from cx_Freeze import setup, Executable 
  
  target = Executable(
      script="main_window.py",
      base = "Win32GUI",
      icon="images\\icon.ico"
      )
  
  setup(name = "DemiurgoXMLgen" , 
      version = "0.1" , 
      description = "" ,
      options={'build_exe': {'include_files': ['images\\']}},
      executables = [target])
  </code></pre>

  <p>I think it has something to do with the <strong>Paramiko</strong> package I am using in my application. Has anyone encountered and solved this problem?</p>
