Redmine

Hello, I have a trouble with an installation of mysql2 adapter with the redmine 1.1.2 workign under the passenger 3.0.7.

I've got the following exception from the passenger's log:

[ pid=15657 thr=84390610 file=utils.rb:176 time=2011-05-20 12:11:37.439 ]: *** Exception RuntimeError in PhusionPassenger::ClassicRails::ApplicationSpawner (Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (no such file to load -- active_record/connection_adapters/mysql2_adapter)) (process 15657, thread #<Thread:0xa0f65a4>):

I seems that it can't find installed mysql2 adapter and ask to install the adapter as follows:
gem install activerecord-mysql2-adapter

But some of people said that run of the: gem install mysql2 is enough to work with rails (may be do not with redmine). What can I do to allow the adapter work?

This is my mysql2 adapter's place:

ls /usr/local/lib/ruby/gems/1.9.1/gems/mysql2-0.3.2/lib/active_record/connection_adapters/
em_mysql2_adapter.rb

My database conf:

# MySQL (default setup).

production:
  adapter: mysql2
  database: redmine1
  host: localhost
  username: redmine
  password: xxxxxxxxxxxxxx
  encoding: utf8

development:
  adapter: mysql2
  database: redmine_development
  host: localhost
  username: redmine
  password: xxxxxxxxxxxxxx
  encoding: utf8

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql
  database: redmine_test
  host: localhost
  username: root
  password:
  encoding: utf8
