Yes, I'm building PHP from scratch with the above mentioned configure
command.

I think that in order to reproduce this you need to add --enable-debug
to your ./configure, as so (I just tried this):

$ ./configure --disable-all --enable-pdo
--with-pdo-mysql=shared,mysqlnd --enable-debug
$ make
$ sapi/cli/php -d extension_dir=modules/ -d extension=pdo_mysql.so -m
PHP Warning:  PHP Startup: Unable to load dynamic library
'modules/pdo_mysql.so' - modules/pdo_mysql.so: undefined symbol:
mysqlnd_debug_init in Unknown on line 0

I assume that ext/mysqlnd/mysqlnd_debug.c needs to be added as a build
dependency of pdo_mysql if --enable-debug is set, but I am not
experienced enough with autoconf et al to figure this out exactly. 

Thanks,
Shahar.

Are you loading the module into a PHP which has mysqlnd enabled?
Usually mysqlnd is automatically activated once another extension using
mysqlnd is being activated.

I tried the following which worked:

$ ./configure --disable-all --enable-pdo
--with-pdo-mysql=shared,mysqlnd
$ make
$ sapi/cli/php -d extension_dir=modules/ -d extension=pdo_mysql.so -m

Description:
------------
I'm putting this under PDO even though this is probably a mysqlnd/build
issue.
 
I've compiled PHP5.3.0-RC1 with --enable-debug and
--enable-pdo-mysql=mysqlnd,shared. When I try to load the PDO MySQL
extension I get this:

PHP Warning:  PHP Startup: Unable to load dynamic library
'/usr/local/lib/php/extensions/debug-non-zts-20090115/pdo_mysql.so' -
/usr/local/lib/php/extensions/debug-non-zts-20090115/pdo_mysql.so:
undefined symbol: mysqlnd_debug_init in Unknown on line 0
