Artweb-design adva cms

While trying to follow instructions with installation it breaks at some point and dont't want to move any further.

Process: rails advacmstest -d mysql -m http://github.com/svenfuchs/adva...

    applying  template: http://github.com/svenfuchs/adva_cms/raw/master/templates/adva-cms.master.rb
        file  script/test-adva-cms
     running  git clone git://github.com/svenfuchs/adva_cms.git vendor/adva # this might take a bit, grab a coffee meanwhile :)
Checking out files: 100% (2780/2780), done.
        rake  adva:install:core -R vendor/adva/engines/adva_cms/lib/tasks
rake aborted!
Don't know how to build task 'adva:install:core'

(See full trace by running task with --trace)

Thanks for installing adva-cms!

We've performed the following tasks:

* created a fresh Rails app
* cloned adva-cms to vendor/adva
* installed adva-cms' core engines to vendor/plugins
* installed adva-cms' images, javascripts, stylesheets to public/

You can now do:

cd advacmstest
ruby script/server
open http://localhost:3000

You should see adva-cms installation screen.
Fill out the form and you're started, enjoy!

     applied  http://github.com/svenfuchs/adva_cms/raw/master/templates/adva-cms.master.rb

And at this point I went to application direcotry and tried: rake adva:install:core -R vendor/adva/engines/adva_cms/lib/tasks

result:

I've got: Ruby: 1.8.7 Rails: 2.3.2 Gem: 1.3.2
