"bundle not found" in capistrano deploy for rails 3.1.3 - ruby-on-rails

Question

Here is the part of message from cap deploy:
** [out :: 176.195.225.93] /home/cj/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `

There are a few posts for the same issue and none of the solution worked. We set default in deploy.rb like:
set :default_environment, {
'PATH' => "/home/cj/.rvm/gems/ruby-1.9.3-p125/bin/:$PATH",
'BUNDLE_PATH' => '/home/cj/.rvm/gems/ruby-1.9.3-p125/bin/'
}
But the cap still have problem finding bundle.
Any help is appreciated. Thanks so much.
UPDATE:
here is the output of bundle -v under /var/www/byop:
Bundler version 1.0.22

The problem may be that you need to create the bundler wrapper. You can do that this way(in your deploy.rb, for example)
require "rvm/capistrano" # http://beginrescueend.com/integration/capistrano/
# rvm-capistrano settings
set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*\//,"")
namespace :rvm do
task :create_bundle_wrapper, roles: :app do
run "rvm wrapper #{rvm_ruby_string} bundle bundle"
end
end
after "deploy:create_symlink", "rvm:create_bundle_wrapper"
