I have a ticket with the same thing - is this your ticket (CS150663)? In that ticket this is the answer:
The solution in this case is to run this:
# yum update -y
This is because multilib is the term Red Hat (and CentOS of course) use for a 64-bit system which also has 32-bit libraries. We require for running the 32-bit installer and agent. The packaging system won't install a newer version of the 32-bit library than the 64-bit version. That is what is happening here, so a system update will resolve this - rerun the agent install after that.
