I successfully installed Redmine today. I tried to install the Gitosis plugin as described [here](http://www.x2on.de/2011/04/23/tutorial-redmine-with-git-and-gitosis-on-ubuntu-11-04/). When i run the command `sudo -u www-data X_DEBIAN_SITEID=default RAILS_ENV=production rake db:migrate:plugins` i get this error:

```

Please install RDoc 2.4.2+ to generate documentation.
rake aborted!
no such file to load -- inifile

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

```

i installed inifile with `gem install inifile` as it is described in the tutorial, but it still occurs.

any help?
