I'm trying to create a new issuetracker integration using soap, and I have an issue

I can see this error under the logs :
userlog0.log:require_once(SoapClient.class.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory - in /DT/testlink/www/testlink-1.9.4.des/lib/functions/common.php - Line 99
I've installed php-soap:
php-soap.i386 5.2.17-jason.2 installed
but still no file SoapClient.class.php on disk

I'm using Centos 5.8
How have you installed your SoapClient ?
