Twitter bootstrap rails could not find in any of the sources

For my website, I'm using Twitter Bootstrap and it is cool !
So easy to use and my website have a nice look.

I'm using the gem Twitter-bootstrap-rails.
It is working great on my development environment. I followed the step by step and added this to my Gemfile:
gem 'twitter-bootstrap-rails'

Problem
When I deploy on production, I have to do "bundle install". No problem, everything is installed. But when I start the server I have this error:
Could not find twitter-bootstrap-rails-2.2.0 in any of the sources

A little bit surprised, because "bundle install" was ok, and I can see the gem.

Solution
In fact, my Gemfile should look like this:

gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git'

I don't know if the latest build fix this problem or if it's using Git, but it is working!

And that's it!

Paperclip order of params

In my website I'm using Paperclip to take care of the attached files.

I have a model "image" who has many "collections".
A "collection" belongs to a "resolution".

I'm displaying the form of an image with a list of available resolutions.

In the model Collection:
has_attached_file :picture,
    :url => "...",
    :path => "...",
    :styles => { :custom => Proc.new { |col| "#{col.resolution.width}x#{col.resolution.height}" }}
   }}

Problem
When an image is updated, the Proc is executed and I have a "nil" exception.
I'm wondering why "resolution" is nil because the params contain a resolution_id.

Solution
In fact, it depends of the order you pass the parameters.

At first, the view was like this :
= f.file_field :picture
= f.hidden_field :resolution_id

But I should do like this:
= f.hidden_field :resolution_id
= f.file_field :picture


The "resolution_id" should be first !
By doing so, Rais is creating the relation between "resolution" and "collection" first, and then he is applying the style.

So, sometimes the order of the params is important!

And that's it!

Edit
Too bad for me, in fact the order is not sure... It is working on my development environment, but not in my production environment...
