It looks like '/usr/local/lib' isn't in the library search path.  If  
you're running on some versions of Linux, you'll need to update the  
ld.so cache after installing GNU Radio:

$ cat /etc/ld.so.conf
--> if /usr/local/lib isn't in this file, then do the following 3  
commands; otherwise, go to the end and run that command:
$ cp /etc/ld.so.conf /tmp/ld.so.conf
$ echo /usr/local/lib >> /tmp/ld.so.conf
$ sudo mv /tmp/ld.so.conf /etc/ld.so.conf

then

$ sudo ldconfig

now try running those GNU Radio scripts again and if it still fails,  
please include your computer's setup info: how you installed GNU  
Radio, OS and version, how you installed background apps and such. - MLD
