Installing on Amazon EC2 instance running CentOS 5 is WAY more esoteric. I spent about 2 hours mucking around until I figured it out, so here it is (this assumes you are already using memcached and have libevent, libzlib, etc installed):
Servers have to be restarted – this has be done before code is deployed or the class won’t exist, which will cause a fatal error.
This process looks harmless, but I had to read 3.7 million blog posts before I found the right path forward.
