Certain Linux distributions do not have this extension included in the minimum PHP package. It can usually be found in one of the "optional" php-* packages.
For CentOS, you will need to run "yum install php-xml", which provides this extension.

On Fedora 16, you can use
yum -y install php-xml
and then be sure to add
extension=dom.so
in the php.ini file for this to work.
You need the DOM MODULE installed if you want to use Youtube Data Api with the Zend GData Library.
Otherwise you cannot obtain a valid Upload Form Token.
