An error occured while installing mysql (2.8.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling.

Has anyone dealt with this particular pain? Your help is eternally appreciated.

    You need to tell bundler where to find the mysql-dev stuff on your box. Usually something like the following will work:

    bundle config build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config

    Of course, you’ll need to replace the path above with your actual path to mysql_config. If you don’t have mysql_config installed then you will need the mysql-dev package installed on your server. It looks like you’re probably on a shared server, so hopefully the development package is already installed. If not, you’ll need to request it.
