Rake db:migrate error: uninitialized constant mysql

Hello,
When I run: rake db:migrate , I get the “uninitialized constant mysql”
error.

I issue the command inside the root of the application InPlaceEditing, a
recipe from Chad F.'s Rails Recipes. The InPlaceEditing application
is inside the directory:

c:\instantrails\rails_apps\InPlaceEditing

I can run the InstantRails Cookbook tutorial, no problem, so MySql
itself is not the problem.

Help will be appreciated!

On my Kubuntu I had the same problem. Try to install libmysql-ruby -
that solved my problem with it.
