I have installed TG using recommended way on Ubuntu 14.04:
sudo pip install virtualenv
sudo virtualenv tgenv
. tgenv/bin/activate
sudo pip install TurboGears2
sudo pip install tg.devtools
gearbox quickstart movies
cd movies
sudo pip install -e .
However starting application ends with following error
(tgenv) petr@home-server:~/movies$ gearbox serve
01:12:43,038 ERROR [gearbox] Failed to load application or server
