I’m going to guess that you have leftover “stuff” from a different attempt to install Gnu Radio, because there’s a file in /usr/bin/gnuradio-companion that is either a symlink-to-nowhere, or it’s pointing to a Python install that doesn’t exist. Now, normally, build-gnuradio uninstalls (via your package manager) any existing Gnu Radio install, but if the package manager doesn’t know about some file (like the /usr/bin/gnuradio-companion) that is apparently installed, it has no way of removing it.

Dear Dong Tian Xiao, Still the best solution (for me) was to install to a clean OS otherwise you might run endlessly about it. Instalation to a clean Ubuntu 14.04 via Pybombs was fast and smooth. I might have a more detail description, if needed, let me know.
