Installing php5-cgi

I am trying to install a new LEMP (Linux,Nginx,MySQL and PHP). Everything I have read says that in order to use PHP's Fast CGI to just run "yum install php5-cgi". I am running this from an Amazon EC2 instance and it just tells me that php5-cgi is not available. I have also tried downloading the source php5 package and running "./configure --with-php5-cgi and it finishes but says: Notice: Following unknown configure options were used: --with-php5-cgi

Any help on what I am doing wrong? I have seen installs using lighthttp's fastcgi but it seems that most recommend you use php's built in version.
