Error while deploying Ruby Application into Stackato - ruby

Question

I am deploying Rack based ruby Application in stackato. Because of local network i have downloaded all my gems locally when i try to push after some stagging i am getting the following error.
Fetching missing gems from RubyGems
staging: http://production.s3.rubygems.org/gems/bundler-1.2.1.gem:
staging: 2013-12-13 01:36:21 ERROR 504: Host production.s3.rubygems.org lookup
failed: Host not found.
staging: wget failed to fetch http://production.s3.rubygems.org/gems/bundler-1.2.1.gem
staging: /home/stackato/stackato/vcap/staging/lib/vcap/staging/plug/gemfile_task.rb:134:in `block in install_gems': Failed fetching missing gems from RubyGems (RuntimeError)
Failed to stage application:
staging plugin exited with non-zero exit code
i thought it is a Gateway error but when i go through my gem list i found
bundler (1.2.1)
if i run bundle install --local --deployment and bundle package it is successfully running the bundle. i have an rbenv here rather than rvm i tried to install bundler at global.
I don't know why it is hitting that host.
Killing my time since three days.
Help me please Thanks in advance
