I installed gnuradio using the build-gnuradio script after I fixed the  libzmq-dev typo.
That's not a typo--Ubuntu, in their infinite wisdom, opted to change the name of that package mid-stream, so there's no way for
  build-gnuradio to really know which one of two will succeed, so it tries both--one of them WILL produce a (non-fatal) error.

The problem appeared after I upgraded from ubuntu 12.04 to ubuntu 14.04 if that helps.
uname -a gives:
3.13.0-79-generic #123-Ubuntu SMP Fri Feb 19 14:27:58 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I had a module that acted as a very simple detector for my receiver that converted a complex number to a binary value (byte output) that worked fine before the upgrade that I have developed with the same method as the tutorial. Now of course it doesn't work. 

I wouldn't send a message if I hadn't spend 3 days on this but now I am really stuck. Please advise.

Thank you
