Can't install PHPMotion

[Anish]

I am not able to install PHPMotion. I am continuosly getting this error while installing

Warning: dl() [function.dl]: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-zts-20060613//../../../../../../home/anish/public_html/coolvids/phpshield/phpshield.5.2.lin' - /usr/local/lib/php/extensions/no-debug-zts-20060613//../../../../../../home/anish/public_html/coolvids/phpshield/phpshield.5.2.lin: undefined symbol: executor_globals in /home/anish/public_html/coolvids/classes/config.php on line 2

Does anyone know what stuff is this?
