Centos – Installing PHP PECL memcached extension on CentOS 5.6

I would like to setup memcached on my server so that I can learn how to use it. It is my understanding that the basic requirements to use it with PHP are:

• PHP
• memcached
• PHP PECL memcached library

After successfully installing and running php53 via yum, I have tried running

yum install php-pecl-memcached

The following is a portion of the output from yum when trying to install php-pecl-memcached:

--> Processing Conflict: php53-common conflicts php-common

I need to stick with php 5.3 so I cannot fall back to the yum php package (php 5.1).

It seems that there was a IUS repo with a package named php53u, according to this site, but I can't use that repo.

I would also like to avoid installing from source.

Is there a solution out there for installing the PECL memcached extension on CentOS 5.6, with PHP 5.3?
