Hi all!

I can't get current redmine master to work with ruby 1.9.


> RAILS_ENV=production  rake db:drop
!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
Couldn't drop redmine19 : #<LoadError: cannot load such file -- mysql>

Additional informations

I tried to install both mysql and mysql2 gems with and without option --with-mysql-config=/usr/bin/mysql_config but it still fails.

The database is not hosted on the same system but mysql libraries and client are installed (mysql command-line works fine):

> dpkg --get-selections |grep mysql
libdbd-mysql-perl                               install
libmysqlclient-dev                              install
libmysqlclient16                                install
mysql-client-5.1                                install
mysql-client-core-5.1                           install
mysql-common                                    install
mysql-server-5.1                                deinstall
php5-mysql                                      deinstall
