Bundler and hidden gems

I have an interesting error when installing gems directly from github (:git => 'whatever').

Firstly, when I remove all gems and run bundle install command, I get the following:

Installing gem1
Installing gem2
Using gem3 (the one from github)

Then when I want to check what I've got I see the following by using gem list:

gem1 (x.x.x)
gem2 (y.y.y)

No gem3... now, looking closer to the file system, I see the following:

ls -l ~/.rvm/gems/ruby-1.9.3-p125/gems
gem1
gem2

So where is gem 3? Not where I'm expecting it to be:

ls -l ~/.rvm/gems/ruby-1.9.3-p125/bundler/gems
gem3-213213213

So it goes under bundler/gems and is not visible to gem list... and by Capistrano deploy, which gives me following:

git://github.com/author/gem3.git (at master) is not checked out. Please run `bundle install`

I'm more worried about Capistrano unable to deploy... Anyone has any clues?

Bundler gets its gems from various sources on your system. As long as they are the correct version, it will pull them in.

When deploying, it has more strict/conservative behavior.

From bundle help install, in the section about Deployment Mode, which is used when the --deployment flag is specified:

Gems are installed to vendor/bundle not your default system loca- tion

In development, it's convenient to share the gems used in your application with other applications and other scripts run on the system.

In deployment, isolation is a more important default. In addition, the user deploying the application may not have permission to install gems to the system, or the web server may not have permis- sion to read them.

As a result, bundle install --deployment installs gems to the ven- dor/bundle directory in the application. This may be overridden using the --path option.
