Answering my own question. Problem was caused by libraries under /usr/local/lib. I resolved it this way: roger@homepc2:~$ sudo -i root@homepc2:~# cd /usr/local/ root@homepc2:/usr/local# tar zcf lib.tar.gz lib/ root@homepc2:/usr/local# rm -fr lib/ root@homepc2:~# ldconfig root@homepc2:~# logout roger@homepc2:~$ gnuradio-companion <<< Welcome to GNU Radio Companion 3.8.0.0 >>> etc.
