It looks like there's a version issue with your installation. You're
trying to install and run 3.6.2 (from git, I assume), but something is
looking for libgnuradio-cvsd-vocoder, which a) is from 3.4.2 here and
b) doesn't exist any longer. All vocoders are now in

I suggest uninstalling and removing any old GNU Radio install files
from your system (there is information on the webpage and in the
mailing list about how to do this) and reinstall 3.6.2.
