glibc error upgrading from 4.5.5 to 4.5.10 on CentOS 4.4

I was performing an upgrade and all seemed to go well until I saw this:

It looks like there is a new DBI.so being installed that expects glibc 2.4. Am I right on this? Is there another work around? I would have to do a major upgrade to get glibc 2.4 ( I don't feel lik egoing through the pain of installing it in addition to what is there ... that always turns into a nightmare) Could I get a DBI.so linked against glibc 2.3?

I forgot to add that we are using the NETWORK edition. If I need to put this in through support please let me know.
Thanks

My mistake I downloaded the wrong one. We have moved to RHEL 5 on all of our boxes except Zimbra and I wasn't paying attention and downloaded the RHEL 5 version.
