I need someone help me, why I can’t run example from this page:

When I run example 1:Dial Tone Output.
I get error message:
Traceback (most recent call last):
File "am.py", line 20, in <module>
fg = build_graph ()
File "am.py", line 10, in build_graph
fg = gr.flow_graph ()
AttributeError: 'module' object has no attribute 'flow_graph'
This example will no longer work with the current SVN trunk (assuming
that's what you're using), because the "flow_graph" code has been
removed. Someone needs to update that page ;) ... or create a
backwards compatible "flow_graph" interpretation layer.
When I run example 2:A Complete FM Receiver
I get error message:
Traceback (most recent call last):
File "test.py", line 5, in <module>
from gnuradio import mc4020
ImportError: cannot import name mc4020
Could be a number of problems:
+ The module "mc4020" is wasn't compiled / installed in the first place;
+ PYTHONPATH isn't correct to find it;
+ code is too old, and no longer works with the SVN trunk (or release
tarball).
