I am having an issue getting php53-mysql to work. I have SLES 11 SP 2 with php53 installed. Everything works fine until I try and add php53-mysql. Then php breaks because of mysqlnd missing.

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php5/extensions/pdo_mysql.so' - /usr/lib64/php5/extensions/pdo_mysql.so: undefined symbol: mysqlnd_allocator in Unknown on line 0
PHP Warning: Cannot load module 'mysql' because required module 'mysqlnd' is not loaded in Unknown on line 0
symbol lookup error: /usr/lib64/php5/extensions/mysqli.so: undefined symbol: mysqlnd_get_client_info

Everything I have read about this error states php has to be built with an environment variable set.
