I was trying to use the ggmsk-test.py, from the gnuradio-example directory,
and got the following error message:

TypeError: firdes_gaussian() takes exactly 4 arguments (5 given)
Can this test script still be used?
The example directory does not include a ./payload.dat file, so I generated
a file with just numbers using a text editor. One numerical value, float
type, per line.
