and memcached installed with following packages:
[root@ ~]# rpm -qa|grep memcached

memcached-1.4.5-1.el5
libmemcached-0.31-1.1.el5

when i do [root@~]# php -v
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/memcache.so' - /usr/lib64/php/modules/memcache.so: cannot open shared object file: No such file or directory in Unknown on line 0

This server has older php and mysql packages, please help me setup php-pecl and memcache extensions on it.

Thanks in Advanced..
