[Discuss-gnuradio] Tutorial: PSK Symbol Recovery - test 3 - qa_qpsk_demod (Failed)

Hi,

Using Ubuntu 16.10 with GnuRadio 3.7.9, installed from the repo, I was trying to follow the Guided tutorial PSK Symbol Recovery.

I cloned it from github https://github.com/gnuradio/gr-tutorial.git and then compiled it:

user@pc:~/$ git clone  https://github.com/gnuradio/gr-tutorial.git
user@pc:~/$ cd gr-tutorial
user@pc:~/gr-tutorial$ cmake .
user@pc:~/gr-tutorial$ make
user@pc:~/gr-tutorial$ make test-tutorial
user@pc:~/gr-tutorial$ make test
Running tests...
Test project /home/user/gr-tutorial

    Start 4: qa_multiply_py_ff

    Start 5: qa_qpsk_demod_py_cb
5/5 Test #5: qa_qpsk_demod_py_cb ..............   Passed    0.17 sec

80% tests passed, 1 tests failed out of 5

Total Test time (real) =   0.80 sec

The following tests FAILED:
      3 - qa_qpsk_demod (Failed)
Errors while running CTest
Makefile:127: recipe for target 'test' failed
make: *** [test] Error 8

From grc-companion, Some of the .grc files (i.e. my_qpsk_demod.grc) try to import tutorial_swig and fail:
    from tutorial_swig import *
ImportError: No module named tutorial_swig

I tried to compile tutorial_swig manually but, when I run "make" nothing seems to happen.
Am I missing steps?

Thanks,

Murray
