UCLA zigbee problem

hello,everyone.
i have installed on ubuntu 10.04 gnuradio 3.3.0 and usrp.There’s no
error in testing examples.
After i installed the ucla_zigbee,when a try to run an example,python
return this error:
byond@byond-laptop:~/ucla_zigbee_phy/src/examples$ ./cc2420_txtest.py -h
Traceback (most recent call last):
File “./cc2420_txtest.py”, line 11, in
from gnuradio import ucla
ImportError: cannot import name ucla

There are no errors when process"./configure", “make” and “make
check”,but i cant find ucla-lib in the path
/usr/local/lib/python2.6/site-packages or disk-packages

Can you help me? Thanks very much.
PS:I have only one version of python
