準備
準備といってもやるべきことはひとつだけです。BundlerにはあらかじめCapistrano用のcapタスクが用意されているので、$RAILS_ROOT/config/deploy.rbの中からrequireします。

実行
cap deployを実行すると、デプロイ後にbundle installが実行されます。
That's it! Running cap deploy will now automatically run bundle install on the remote server with deployment-friendly options. As list of options that can be changed is available in the help for the cap task. To see it, run cap -e bundle:install.

cap -e bundle:installしてみました。
$ bundle exec cap -e bundle:install

cap bundle:install

Install the current Bundler environment. By default, gems will be installed to
the shared/bundle path. Gems in the development and test group will not be
installed. The install command is executed with the --deployment and --quiet
flags. If the bundle cmd cannot be found then you can override the bundle_cmd
variable to specifiy which one it should use.
You can override any of these defaults by setting the variables shown below.
N.B. bundle_roles must be defined before you require 'bundler/capistrano' in
your deploy.rb file.
set :bundle_gemfile, "Gemfile"
set :bundle_dir, File.join(fetch(:shared_path), 'bundle')
set :bundle_flags, "--deployment --quiet"
set :bundle_without, [:development, :test]
set :bundle_cmd, "bundle" # e.g. "/opt/ruby/bin/bundle"
set :bundle_roles, {:except => {:no_release => true}} # e.g. [:app, :batch]
インストール先
デフォルトでは#{shared_path}/bundleディレクトリにインストールされます。
$ ls /var/www/myapp/shared
bundle
