can it be a permission problem?
I tried added a print before the error and discovered this file it located
succesfully many times when I use grc:

ImportError: libgnuradio-extras.so: cannot open shared object file: No such

as you can see, when it does not work, file pointer is at a completely
different address (0x9######) and when it works the file pointer is at
address of 0xd######
also, I use tried to use sudo command, but it did not work.
any ideas?
Thanks for all the advice
Guy
