Rails 4 app deployment using mina on webfaction

Question

I have a rails 4 application that I am trying to deploy on webfaction. The app resides on bitbucket. Also, as per the webfaction documents, the app has to be deployed in the '/home/username/webapps/app' path. I have all my database.yml setting(for all envs) in secrets.yml which has been copied to the shared_path/config.

As per the documentation specified http://docs.webfaction.com/software/rails.html, the some environment variables have to be set. Webfaction needs you to set the env variables which are destroyed after the ssh session is over. I have tried to set them in the 'set_env_variables' task.

the directory structure is as:

$ pwd
/home/username/webapps/appname
$ ls
bin  gems  hello_world  lib  nginx  releases  scm  shared  src  tmp
$ls gems/
bin  build_info  cache  doc  extensions  gems  specifications
$ ls gems/gems/
actionmailer-4.1.8         bundler-1.7.9               jbuilder-2.2.5      rack-test-0.6.2        sass-rails-4.0.5       tilt-1.4.1 ...
$ cd hello_world/
[hello_world]$ bundle
-bash: bundle: command not found
$ cd ..
$ pwd
/home/username/webapps/appname
$ export PATH=$PWD/bin:$PATH
$ export GEM_HOME=$PWD/gems
$ export RUBYLIB=$PWD/lib
$ cd hello_world/
$ bundle
Using rake 10.4.2
...
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.

It specifies that we need to set the env variables.

Here 'hello_world' is a sample rails application that webfaction has provided. I would be removing it. nginx-passenger are provided too. My deployment script is as

require 'mina/bundler'
require 'mina/rails'
require 'mina/git'

set :domain, 'webabc.webfaction.com'
set :deploy_to, '/home/username/webapps/appname'
set :repository, 'git@bitbucket.org:username/appname.git'
set :branch, 'master'

set :shared_paths, ['config/secrets.yml', 'log', 'tmp']
set :user, 'ssh-username'    # Username in the server to SSH to.

task :environment do
end

task :setup => :environment do
  queue! %[mkdir -p "#{deploy_to}/#{shared_path}/tmp"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/tmp"]

  queue! %[mkdir -p "#{deploy_to}/#{shared_path}/log"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/log"]

  queue! %[mkdir -p "#{deploy_to}/#{shared_path}/config"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/config"]

  queue! %[touch "#{deploy_to}/#{shared_path}/config/secrets.yml"]
  queue  %[echo "-----> Be sure to edit '#{deploy_to}/#{shared_path}/config/secrets.yml'."]
end

desc "Deploys the current version to the server."
task :deploy => :environment do
  deploy do
    invoke :'set_env_variables'
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    to :launch do
      queue "mkdir -p #{deploy_to}/#{current_path}/tmp/"
      queue "touch #{deploy_to}/#{current_path}/tmp/restart.txt"
      invoke :restart
    end
  end
end

desc "Set the environment variables."
task :set_env_variables => :environment do
  queue! "cd /home/username/webapps/appname"
  queue! "export GEM_HOME=$PWD/gems"
  queue! "export RUBYLIB=$PWD/lib"
  queue! "export PATH=$PWD/bin:$PATH"
  queue! "export LD_LIBRARY_PATH=$HOME/lib/"
end

When I do 'mina deploy --verbose --trace', I get
