I found this and worked out perfectly:

you can go to http://www.tmtm.org/en/ruby/mysql/ to download the tar file, and run the command below

# ruby ./install.rb

to install the mysql.rb

Well... This command line gives me an error : "./install.rb:9: Use RbConfig instead of obsolete and deprecated Config." What's wrong ?
When I posted this answer I was using Ruby 1.8.7 and maybe I was still using Rails 3.2.10 but what I recommend now is: 1) Install mysql from dev.mysql.com/downloads then manage your ruby versions with rvm and install your mysql gem through rvm. Side note: sometimes you should use mysql2 gem instead of mysql gem.

Use the following it worked with me

brew install mysql

Do you have the Xcode developer tools installed on Mac OS X? If not, I'd start there.

You can download them here: http://developer.apple.com/technologies/xcode.html

Once you've installed that, try again.

You need the mysql development libs to compile it. If you were on linux you could use "yum install mysql-devel". Not sure about how to get them installed on a mac, but try downloading the connector libraries from here: MySql Connector Downloads

You may have to pass in a --with-mysql-libs option to point to the directory when the C libraries are unpacked to. Hope this points you in the right direction.

Or you can just put the libraries in the default directory: /usr/lib64/mysql
