So what was the result? Did the `sudo apt-get remove gnuradio` succeed? Do you 
still have libgnuradio-* packages installed on your system? Provide the output 
of 

    dpkg -l | grep gnuradio

This is OK. This library was not install by gnuradio's package so you can't 
remove it by removing the gnuradio package. So after you've removed all 
gnuradio packages you need to check if there are any leftovers by running

   find /usr -name *gnuradio* 

and if there is none then you need to do a clean rebuild of your OOT and then 
reinstall

   source /home/mariom/prefix-3.8/setup_env.sh
   cd /home/mariom/gr-tutorial/
   rm -rf build/
   mkdir build
   cd build
   cmake -DCMAKE_INSTALL_PREFIX=/home/mariom/prefix-3.8/ ..
   make install

So you have two prefixes - `prefix-3.8` and `prefix-3.8.3.1`. This is OK as 
long as you are careful where you install things. You should not mix two 
prefixes and source their setup_env.sh scripts at the same time in the same 
terminal.

How do you start gnuradio-companion? If you start it from your prefix then in 
your terminal you first need to source the setup_env.sh file or run `pybombs 
run gnuradio-cmpanion`
