Pylons Helloworld - Erreur «Version attendue dans…» Erreur

Question

J'essaie de démarrer un nouveau projet en utilisant ce doc: http://pylonshq.com/docs/en/1.0/gettingStarted/ (Téléchargez des go-pylons, faites VirtualEnv avec, etc.).

Mais quand j'essaie de démarrer l'application Helloworld, il dit:

$ paster serve --reload development.ini 
Starting subprocess with file monitor

ValueError: ('Expected version spec in', 'srvbakweb/', 'at', '/')

Quelle pourrait être la raison? Comment déboguer cela?

J'utilise Python 2.6 sur Gentoo Linux. J'ai également essayé avec le commutateur - des packages de sites pour les go-pylons et l'installation de pylônes à l'échelle du système. Même erreur :(
