gnuradio 3.3.0 installed but cannot run any script

[haxor@…]

I am having the same problem as in Ticket #28315. My output from port installed | grep gnuradio is the same. However, ls /opt/local/lib/python2.6/site-packages returns:

gnuradio	grc_gnuradio	usrpm

(thus, there is no reference to xcbgen as exists in ticket #28315)

When I restart the shell, I still get the same error when I try to run, for example, usrp_probe:

machinegeekcoms-Mac-mini:~ machinegeekcom$ usrp_probeTraceback (most recent call last):
  File "/opt/local/bin/usrp_probe", line 21, in <module>
    from gnuradio import usrp
ImportError: No module named gnuradio
machinegeekcoms-Mac-mini:~ machinegeekcom$ 

Any assistance will be appreciated.
