For some reason bundler isn't just installing needed gems not already installed. Instead it's re-installing everything in my Gemfile. Is there are way to get it to only install needed gems (they it works for me in development mode).
Capistrano 2.6.0
Bundler 1.0.12
Ubuntu 10.04 server 32-bit
Task Snippet:
task :bundle_gems, :roles => :app do
run "cd #{deploy_to}/current && bundle install --path vendor/gems RAILS_ENV=production"
end
