LP:1003797 - Failed dependencies

cat /etc/*release
CentOS release 6.2 (Final)

I downloaded packages shown below from http://terrier.askmonty.org/archive/pack/5.5-serg/build-2196/kvm-rpm-centos5-x86/rpms/

MariaDB-5.5.23-centos5-i686-client.rpm
MariaDB-5.5.23-centos5-i686-server.rpm
MariaDB-5.5.23-centos5-i686-shared.rpm

I've installed server and shared rpms without any issue.
but once I try to install client rpm via the command shown below, I get an error:

rpm -ivh MariaDB-5.5.23-centos5-i686-client.rpm
error: Failed dependencies:
libreadline.so.5 is needed by MariaDB-client-5.5.23-1.i386

yum install readline
Package readline-6.0-3.el6.i686 already installed and latest version

Please note: I've installed MariaDB 5.3.7 without any issue.
