Problem
When using the god gem in a Rails 2.3.2 application, when you unpack (freeze) the god gem with :

sudo rake gems:unpack

it creates the god drectory in vendor/gems with root owner, and group permissions.

Solution
Remember to change owner and group for the folder

sudo chown -R user_name vendor/gems/god-0.11.0
sudo chown -R user_name vendor/gems/god-0.11.0
