[Wine] can't install wine :(

[gwolf2u]

hello guys,

I have a CentOS distribution installed but seems I can't install wine with the yum command 
I have tried 

Code:
yum install wine

 
but no go 
it outputs 

Code:

Loaded plugins: fastestmirror, priorities
Loading mirror speeds from cached hostfile
 * rpmforge: fr2.rpmfind.net
Excluding Packages in global exclude list
Finished
Setting up Install Process
Parsing package install arguments
No package wine available.
Nothing to do




what should I do
note that I'm no expert in linux so any help is highly appreciated
