Please try using this CVS snapshot:
http://snaps.php.net/php5.3-latest.tar.gz
For Windows:
http://windows.php.net/snapshots/
I still didn't reproduce it but applied a patch with some guessing.
Please try the snapshot and see whether it helps.

Ah, the debug piece is important, investigating ...

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
