You are using the pure ruby mysql.rb driver. Sequel requires the C
based mysql.so driver. You want to gem install mysql (or install from
source), and make sure to remove the mysql.rb file or call gem
('mysql') to force the use of the gem.
This error is common enough that I should write have Sequel check for
it and report a better error.
