Run 'ctest -V -R volk' and post the output to help us figure out
what's going wrong there.

You're using 3.7, which changed the structure of the modules. The
'firdes' Python module is now underneath the 'filter' module. So you
have to make sure you do:

from gnuradio import filter
from gnuradio.filter import firdes

You can now use 'filter.firdes....' or just 'firdes...'.
