Mysql.bundle problem

I’m not sure what is going on, but anytime I try to use the mysql class
I get this error:

/opt/local/lib/ruby/site_ruby/1.8/powerpc-darwin8/mysql.bundle:
dlopen(/opt/local/lib/ruby/site_ruby/1.8/powerpc-darwin8/mysql.bundle,
9): Library not loaded: /usr/local/mysql/lib/libmysqlclient.15.dylib
(LoadError)

Reason: image not found -
/opt/local/lib/ruby/site_ruby/1.8/powerpc-darwin8/mysql.bundle
from checkdb.rb:1

I’m using Mac OSX Leopard and the mysql-2.7 gem. Any Ideas?
