I have been trying to connect to MySQL thru rails. Initially I had  
rails 2.1.2 and upgraded to rails 2.2 to use RestAPI in sproutcore.  
Once I have upgraded my rails version to 2.2, I have been getting this  
error. All I did is the following:

1. rails addressbook
2. cd addressbook
3. script/generate scaffold Contact first\_name:string lastname:string
4. rake db:migrate

I also change the database.yml to suite MySQL.

I have been getting the below error. Could someone please help me  
resolve this issue

ERROR:  
srilatha-bhuvanapallis-macbook-pro:contacts Latha$ rake db:migrate(in /  
Users/Latha/LearnSproutCore/AddressBookWithDatabase/contacts)  
!!! The bundled mysql.rb driver has been removed from Rails 2.2.  
Please install the mysql gem and try again: gem install mysql.  
rake aborted!  
no such file to load – mysql

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

Thanks in advance  
Latha
