Download phpredis source code from https://github.com/nicolasff/phpredis git clone git://github.com/nicolasff/phpredis.git
By default, compiling PHP extension on OSX Lion will generate a 64bit binary. However, Zend Server CE only support PHP 32bit. Therefore, I must compile phpredis in 32bit architecture. phpize ./configure CFLAGS="-arch i386" make

Restart Zend Server CE: sudo /usr/local/zend/bin/zendctl.sh restart-apache
