Steps, problems, and solutions for installing memcached through yum in centos 5.5

1. Install epel Repo

Rpm-uvhHttp://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

2. Install memcache
Yum-y install memcached

The following problems may occur during installation:
--> Missing dependency: Perl (net: ssleay)> = 1.33 is needed by package perl-AnyEvent-5.240-1.el5.rf.noarch (rpmforge)
Error: Missing dependency: Perl (net: ssleay)> = 1.33 is needed by package perl-AnyEvent-5.240-1.el5.rf.noarch (rpmforge)
You cocould try using -- skip-broken to work around the problem
You cocould try running: Package-cleanup -- Problems
Package-cleanup -- dupes
Rpm-va -- nofiles -- nodigest
The program package-cleanup is found in the Yum-utils package.

This problem is because centos Yum does not have the latest Perl-net-ssleay and Perl-io-socket-SSL packages required by memcached.
The solution is also simple. Delete the old package and install the new package.
