[mod_python] ImportError: No module named index

Using:
Apache-2.0.46
python-2.2.3-r5
mod_python-3.1b

Apache conf:
<Directory /home/httpd/htdocs/python>
        SetHandler mod_python
        PythonHandler mod_python.publisher
        #PythonDebug On
</Directory>

new.py
from mod_python import apache

def index(req):
	return "Hello World!"

Error_log:
PythonHandler mod_python.publisher: ImportError: No module named index


Any ideas ?
