php_pdo 5.2 Drupal 7 OpenBSD 5.1

[Jim Barchuk <jb@xxxxxxxxxxxx>]

Hi All!

Simplest Q, is there a way to test (via CLI or a short script) whether 
pdo-mysql is -truly- installed and functional?

I'm using OpenBSD 5.1 but want to use a few newer versions of some 
software. For example OBSD provides phpMyAdmin 3.4.9 but with a few 
oddities I have manually installed 3.5.2.2.

My issue is with Drupal 7. (OBSD provides 6.24.)

The Drupal install fails with:

Requirements problem
Database support	Disabled
Your web server does not appear to support any common PDO database 
extensions. Check with your hosting provider to see if they support PDO 
(PHP Data Objects) and offer any databases that Drupal supports.

There's a link in that text that points to 
http://drupal.org/node/270#database which says "Drupal 7 notes... PHP Data 
Objects (PDO) must be activated for Drupal 7 to install and run correctly. 
Look in your php.ini. Uncomment (remove the leading semicolon) at line 
extension=php_pdo.dll, extension=php_pdo_mysql.dll. In Linux, these would 
be extension=pdo.so and extension=pdo_mysql.so. Some Linux distributions 
may have these extensions by default in files found in the conf.d folder 
(Ubuntu 12.04: /etc/php5/conf.d has pdo.ini and pdo_mysql.ini). If these 
lines are not there, you will need to add them."

So I added those lines, and httpd restart returns "PHP Warning:  PHP 
Startup: Unable to load dynamic library 
'/usr/local/lib/php-5.2/modules;/usr/local/share/php-5.2/include/ext/pdo/pdo.so' 
- File not found in Unknown on line 0" which makes sense because I don't 
find a pdo.so anywhere.

On the plus side phpinfo.php reports...
PHP Version 5.2.17 Configure Command
--with-pdo-mysql=shared,/usr/local

...so I don't think I should even -need- the explicit 'extension' line if 
it's already --with'ed into the original configure.

I don't know if an OBSD pkg install of Drupal (6) would install the *.so, 
and/or perform other PHP configuration adjustments.

I don't know exactly how the Drupal install is looking for the pdo - the 
configure says it is, but I can't find it in an extension file. If there 
-is- no extension file then I don't know if the Drupal install fail is 
caused by simply not finding a file, or trying and failing to run an 
actual functional test.

My intent is to find out if the pdo facility is installed at all. If it is 
then I'll look into why the Drupal install can't find it.

Thanks much. Have a :) day!
