On a default 7.2 load this is not installed. Are you sure you installed it? Please do a:
pear list
and confirm you can see it. If not, then it's not installed and you will need to - pear install channel://pear.php.net/HTTP_WebDAV_Server-1.0.0RC4 to install it as it is still a beta package, or create yourself a set of RPMS and put then in the correct place.
