Description: ------------ The package for PDO-beta has PDO as "PDO" and the packages for PDO_{database type} require "pdo" so they are failing on the pear install. Reproduce code: --------------- gentoo dev-php # pear help version PEAR Version: 1.3.5 PHP Version: 5.0.3 Zend Engine Version: 2.0.3 Running on: Linux gentoo 2.6.10-gentoo-r6 #1 SMP Thu Jan 20 22:19:58 PST 2005 i686 gentoo dev-php # pear install pdo-beta ...

This is not because I've not installed the pdo extension in php.ini.
