undefined method `init' for Mysql:Class error

[Paul Barker]

Hi,

I'm trying to set up just a basic blog on my webhost so I can just get everything working before I do more but I keep getting this error when I go add tables to the database via command line:

rake db:migrate

rake aborted!
undefined method `init' for Mysql:Class

(See full trace by running task with --trace)
[e-mail] [~/etc/rails_apps/blog2]#
[e-mail] [~/etc/rails_apps/blog2]# rake db:migrate --trace
(in /home/efroggyc/etc/rails_apps/blog2)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
rake aborted!
