Undefined local variable or method `globalize_options'


I was recommended to post my questions here by Sven F… I know I18n
which I use since a couple of months for both http://radiopodcast.fr
(+ it’s upcoming iPhone app) and the backend of the upcoming
SevenSnap.com iPhone App. But I started looking into using Globalize2
for localizing Models (basically Product Descriptions) and I ran into
2 problems:

#1 - The sample app isn’t running, giving some fallback or else errors
#2 - Integrating in my App works but as long as I try using one of the
plugins mentionned on the globalize2 page I got the error specified in
the subject.

Can anybody help?
