php-pdo and version downgrades

[Stephen Borrill <netbsd%precedence.co.uk@localhost>]

The php_pdo* packages have not kept step with PHP changes. The PDO 
components are now built into PHP rather than maintained separately in 
PECL. However, pkgsrc is still using the old PECL source which is 
unmaintained and hasn't been altered for 3 years. This is confusing as the 
package versions report themselves to be 5.2.9.1.0.2, etc. but they are in 
fact based on the 5.1.x code-base.

I've fixed all the php_pdo* packages, but as part of doing this the PECL 
version number will get stripped off the end meaning that the new version 
numbers are just 5.2.9 instead of 5.2.9.1.0.2 (for example). 
Unfortunately, 5.2.9{,nb1} is considered to be older than 5.2.9.1.0.2 
meaning that it will appear as though a downgrade has taken place.

How should I address this?
