You have to set the PYTHONPATH. This is not a GRC problem, this is a 
gnuradio installation problem. I bet that if you try to run other 
gnuradio apps, you will see a similar problem.

Read the part about the PYTHONPATH

The generated code is in the same folder as your saved flow graph. By 
default, its called top_block.py


Source code for modulators are here:
