"limit_req_zone" unknown directive in Nginx

[partysoft]

Hi i have CENT OS and installed nginx from RPM 

using this guide, all works fine except it doesn't have some basic modules

http://www.cyberciti.biz/faq/rhel-fedora-install-configure-nginx-php5/

i get 

 unknown directive "limit_req_zone" in /etc/nginx/nginx.conf

i used for example limit_zone  and it works, 

i'm not doing nothing fancy  , just following the examples given on the http://wiki.nginx.org/NginxHttpLimitReqModule

is there anyway to include a compiled .so or something like that of that module? i think it's just isn't compiled or something...



Here's the version i'm getting with nginx -V

nginx version: nginx/0.6.39
