PHP does not start OpenSuse-Linux [vers. 11.3]

Hello Community, good evening!

i am having troubles with starting PHP on linux - [running OpenSuse-Linux]

Could not open input file: -
suse-linux:/usr/perl # php -v
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/extensions/' 
- cannot open shared object file: No such file or directory in Unknown on line 0
PHP 5.3.4-dev (cli)

suse-linux:/usr/perl # 

well what is wrong hereā€¦?

Install the php5-readline package. As you would expect.
