(It looks like you have a library conflict) rpm -qf /usr/lib64/mysql/* More than likely, you can resolve the problem by removing the package that provides the files in /usr/lib64/mysql/. However, as Alexander pointed out, this isn't a problem with the CentOS packages, and you're more likely to get useful information if you address this question to the vendor of the broken package.
