Re: gr-display "import display" causes error
You should have used: cmake -DCMAKE_INSTALL_PREFIX=/usr You should also use that for any OOT you install.

Is this the problem? Did I choose an incorrect directory for the gnuradio location? BTW if I run "gnuradio-config-info --prefix", the result is "/usr/".
