sys.path is missing library directories in Python 3

[nickjacobson]

What steps will reproduce the problem?

1. Install ActiveState Python 3.4.3.2
2. In Start menu select DreamPie > Add Intepreter and choose C:\Python34\python.exe
3. Open a DreamPie window
4. import sys
5. print(sys.path)

What is the expected result?
sys.path should by default contain 'C:\Python34\lib\site-packages', 'C:\Python34\lib\site-packages\win32', 'C:\Python34\lib\site-packages\win32\lib', and 'C:\Python34\lib\site-packages\PythonWin'. (DreamPie for Python 2.7 does contain the corresponding entries.)

What happens instead?
It only returns: ['', 'C:\Program Files (x86)\DreamPie\data', 'C:\Windows\system32\python34.zip', 'C:\Python34\DLLs', 'C:\Python34\lib', 'C:\Python34'], so the library entries are missing.

Therefore, 3rd party libraries can't be imported until the directories are added to sys.path, every time.

Please provide any additional information below. To submit a screenshot, you can go to imgur.com, upload the image, and paste the URL.

Note that in the Python Interactive Shell for Python 3.4, sys.path by default contains:
['', 'C:\Windows\system32\python34.zip', 'C:\Python34\DLLs', 'C:\Python34\lib', 'C:\Python34', 'C:\Python34\lib\site-packages', 'C:\Python34\lib\site-packages\win32', 'C:\Python34\lib\site-packages\win32\lib', 'C:\Python34\lib\site-packages\Pythonwin']. This is what Dreampie's sys.path should be too.
