modules won't load in snow python 2.7 mac os x /snow leopard

```
What steps will reproduce the problem?
1. downloaded from svn
2. opened properties.config and added
/Applications/Pd-extended.app/Contents/Resources/bin/pd
(previously tested the path in terminal and it did launch PD)
3. opened the example.py ('python
/Users/alkopop79/pythonstuff/pyata/src/example.py

What is the expected output? What do you see instead?

I expected the example file run instead it yielded an error message:

Traceback (most recent call last):
File "./src/example.py", line 13, in
from Pd import *
File "/Users/alkopop79/pythonstuff/pyata/src/Pd.py", line 14, in
from basic_classes.box import *
ImportError: No module named basic_classes.box

What version of the product are you using? On what operating system?

Please provide any additional information below.

Start by running src/example.py in the reported Python 2.7 environment and inspect the import chain from src/example.py through src/Pd.py to basic_classes.box. Confirm why basic_classes.box cannot be found and verify that the example runs without the reported ImportError.
