import lxml.html

Me da un error cuando quiero compilar con cx_freeze:

   Traceback (most recent call last):
  File "C:\Python27\Scripts\cxfreeze", line 5, in <module>
    main()
  File "C:\Python27\lib\site-packages\cx_Freeze\main.py", line 188, in main
    freezer.Freeze()
  File "C:\Python27\lib\site-packages\cx_Freeze\freezer.py", line 572, in Freeze
    self._FreezeExecutable(executable)
  File "C:\Python27\lib\site-packages\cx_Freeze\freezer.py", line 186, in _FreezeExecutable
    exe.copyDependentFiles, scriptModule)
  File "C:\Python27\lib\site-packages\cx_Freeze\freezer.py", line 554, in _WriteModules
    path = os.pathsep.join([origPath] + module.parent.path)
TypeError: can only concatenate list (not "NoneType") to list

Cuando elimino esta importación, todo está bien, pero necesito usar lxml.html, no importarlo no soluciona nada :(
