ladon + uwsgi: unable to load app

Hi,
I am using to publish some API (soap) over the internet.
I would like to use nginx + uwsgi but i am in trouble:
I get this output browsing to the page:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/ladon/server/wsgi_application.py", line 332, in __call__
    self.import_services(self.service_list)
  File "/usr/local/lib/python2.7/dist-packages/ladon/server/wsgi_application.py", line 288, in import_services
    __import__(service)
ImportError: No module named serverL

My CLI is:
uwsgi -s 127.0.0.1:7777 --logto ~/uwsgi.log --wsgi-file /path/scripts/handler.py

handler.py contains:
from ladon.server.wsgi import LadonWSGIApplication
from os.path import abspath,dirname

application = LadonWSGIApplication('serverL','/path/script/src')

from ladon.server.wsgi import LadonWSGIApplication
from os.path import abspath,dirname
application = LadonWSGIApplication('serverL')

and my tree in /path/script:
.
├── handler.py
├── src
│   ├── serverL.py

Thanks in advance
