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.

I used the script from the link below to install Gnuradio :

Following is the log installing GNU Radio, I set the PYTHONPATH , but still cannot find gnuradio companion.
address@hidden:~$ export PYTHONPATH=/usr/local/lib/python2.7/dist-packages
address@hidden:~/gnuradio$ gnuradio-companion

You should probably set your PYTHONPATH to:
/usr/local/lib/python2.7/dist-packages
Using:
export PYTHONPATH=/usr/local/lib/python2.7/dist-packages
in your .bashrc or equivalent file prior to attempting to run
any Gnu Radio applications or Gnu Radio Companion.
