[Discuss-gnuradio] can't use ControlPort in gnuradio 3.7

Hi People,

My system:
 Ubuntu 13.04
 GNURADIO 3.7

I wanted to use ControlPort, but can't:

When I run .py file:

from gnuradio.ctrlport.monitor import *
ImportError: No module named ctrlport.monitor
 

Or

>>> from gnuradio import ctrlport
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name ctrlport

Can you help me?
