установка php-memcached на centos 6.4 с помощью php5.5

Я только что закончил установку php FASTCGI (php-fpm) v.5.5 с помощью Nginx. на новом Centos6.4

Я пытаюсь установить memcached, но сталкиваюсь со многими проблемами..... вот мои шаги:

/bin/rpm -ivh http://ftp.uninett.no/linux/epel/6/i386/epel-release-6-8.noarch.rpm 
/bin/rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
yum --enablerepo=remi,remi-php55 install nginx php-common php-fpm php-mysqlnd

Но при попытке добавить memcached:

yum install php-pecl-memcached.x86_64 (Extension to work with the Memcached caching daemon)

Он терпит неудачу...:
