I have installed MySQL 5.5.8 successfully and mysql2 gem 0.2.6.
but when I execute rake db:create
It tell me:

dlopen(/Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): Library not loaded: /usr/local/mysql/lib/libmysqlclient.16.dylib
  Referenced from: /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
  Reason: Incompatible library version: mysql2.bundle requires version 17.0.0 or later, but libmysqlclient.16.dylib provides version 16.0.0 - /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
/Users/vvdpzz/mayday/Rakefile:4
(See full trace by running task with --trace)

What should I do?
How to fix that?
