Answer 1

Install the PDO module for your database engine, using PECL. For example:

pecl install pdo
pecl install pdo_mysql

And load the extensions in your php.ini file, by adding these lines:

extension=pdo.so
extension=pdo_mysql.so

Answer 2

apt-get should be good for this, and as I recall the PDO version is in the php5-mysql package:

For Debian based OS (apt-get)

sudo apt-get install php5-mysql

For MacPorts

php5-mysql @5.3.8 (php, databases) - a PHP interface to MySQL databases, including the mysql, mysqli and pdo_mysql extensions

sudo port install php5-mysql
