capistrano deploy using jruby - deployment

Question

I have a server that holds multiple rails apps, the majority of them are ruby, wheras there is one app that we use jruby
I always get this error after deploy under passenger:
Could not find rake-10.1.0 in any of the sources (Bundler::GemNotFound)
However, I don't get this when I locally rails s using WEBrick
the deploy script as following:
#server details
default_run_options[:pty] = true
set :user, "xxxxx"
set :scm_passphrase, "yyyyyy"
set :domain, "abc.abc.com"
set :application, "project_adsadsa"
#file path
set :repository, "git#github.com:jjjjjjjj/aaaaaaaa.git"
set :deploy_to, "/var/www/html/jdbc"
# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`
role :web, "ip_address" # Your HTTP server, Apache/etc
role :app, "ip_address" # This may be the same as your `Web` server
role :db, "ip_address", :primary => true # This is where Rails migrations will run
#miscellaneous options
set :rails_env, :development
set :deploy_via, :remote_cache
set :scm, 'git'
set :branch, 'master'
set :scm_verbose, true
set :use_sudo, false
ssh_options[:forward_agent] = true
namespace :deploy do
desc "cause Passenger to initiate a restart"
task :restart do
run "touch #{current_path}/tmp/restart.txt"
end
end
after "deploy:update_code", :bundle_install
after "deploy", :create_symlink
desc "do symlink the db"
task :create_symlink, :roles => :app do
run "ln -s #{shared_path}/development.sqlite3 #{current_path}/db/development.sqlite3"
end
desc "install the necessary prerequisites"
task :bundle_install, :roles => :app do
run "cd #{release_path} && bundle install --without production"
end
