How To Install Perl-XML-Parser

i've to install perl-XML-Parser on my dedicated server. i'm using centOS4.5. i tried

Code:
yum install perl-XML-Parser
after that command i got:


Code:
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
Excluding Packages in global exclude list
Finished
Parsing package install arguments
No Match for argument: perl-XML-Parser
Nothing to do

if anyone asks why i've to install it, i want to install VNC. while installing gnome with that command:

Code:
yum install gnome*
i got that error :

Code:
--> Running transaction check
--> Processing Dependency: perl-XML-Parser for package: intltool
--> Finished Dependency Resolution
Error: Missing Dependency: perl-XML-Parser is needed by package intltool

so, i think that i've to install perl-XML-Parser. but how?
