[Ruby] Vlad issues

[accessing george]

Hi,
I am migrating from capistrano deployment to the no nonsense vlad
unfortunately it really is not easy.

i want to deploy using mongrel cluster proxied to nginx

my *mongrel_cluster.yml* looks like this,
---
cwd: /var/www/app/current
log_file: log/mongrel.log
port: "5000"
environment: production
address: 127.0.0.1
pid_file: /var/www/app/shared/pids/mongrel.pid
servers: 3

my deploy.rb
#vlad recipes for deployment
APP ="app"
set :domain, "domain_ip"
set :deploy_to, "/var/www/#{APP}"
set :repository,  "path_to_repo"

on my rake file i have
begin
    require 'vlad'
    Vlad.load
  rescue LoadError
    # do nothing
  end

I am using the same usernames but different passwords for both development
machine and deployment machine
The subversion repository is on a separate server with a different username
and password and accessible via http

This is the error messaging that i am getting on my development console

Please can someone help me? where could i be wrong?
