Hobo Hobo

I have an error when I want to create a new hobo app with hobo version 1.3.0.pre23.

I work on a Debian lenny.

I followed those steps :

1 - Install Rvm

bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"' >> .bashrc

2 - Install Ruby

rvm install 1.9.2
rvm --default 1.9.2

3 - Install Rails

gem install rails

4 - Install sqlite3

sudo apt-get -t lenny-backports install libsqlite3-dev 
gem install sqlite3-ruby

5 - Install hobo

gem install hobo -v 1.3.0.pre23 --pre

6 - Create a new hobo app

 Hobo Setup Wizard
  Do you want to start the Setup Wizard now?
(Choose 'n' if you need to manually customize any file before running the Wizard.
You can rerun it at any time with `hobo g setup_wizard` from the application root dir.) [y|n] y
