Answer 1

This blog post solved a similar if not the same problem that I was having.

You need to install libmysqlclient-dev in order to build the mysql2 gem.

Answer 2

I had the exact same problems. I resolved them by uninstalling MySQL completely, reinstalling the 64 bit version and installing the mysql2 gem with options pointing to the MySQL install.

I followed some instructions I found at petermac.com:

1. Uninstall MySQL:

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*

edit /etc/hostconfig and remove the line MYSQLCOM=-YES-

sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*

2. Install MySQL 64 bit edition

3. Install mysql2 gem

sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- \
  --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib \
  --with-mysql-include=/usr/local/mysql/include

That should at least get the gem installed :)
