Redmine

Hi,

I'm following that wiki http://wiki.locaweb.com.br/pt-br/Como_instalar_o_Redmine_na_Locaweb

I'm from Brasil and I want to install Redmine in my host. But when I execute:

-bash-4.1$ rake generate_session_store --trace
(in /home/storage/2/69/a2/sultech/rails_apps/redmine)

• Invoke generate_session_store (first_time)
• Invoke config/initializers/session_store.rb (first_time)
• Execute config/initializers/session_store.rb
  rake aborted!
