Redmine

The message I've got in logs is

[Fri May 02 14:10:50.675430 2014] [cgi:error] [pid 5290] [client 127.0.0.1:46347] AH01215: You did not specify how you would like Rails to report deprecation notices for your development environment, please set config.active_support.deprecation to :log at config/environments/development.rb

I've tried to install passanger via apt-get and gem, still the same problem.

My VHost configuration:

<VirtualHost *:80>
    ServerName redmine.localhost
        ServerAdmin webmaster@localhost

        DocumentRoot /usr/share/redmine/public

    #RailsEnv production
    RailsBaseURI /
    PassengerAppRoot /usr/share/redmine/public

        AddHandler cgi-script .cgi .fcgi
        <Directory /usr/share/redmine/public>
                PassengerResolveSymlinksInDocumentRoot on
                Options -Indexes +ExecCGI +FollowSymLinks -MultiViews
                AllowOverride all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Redmine is installed via apt-get. What am I doing wrong?
