[CentOS] Mysql cluster vs. mysql-libs

Hi,
it seems even a minimal install of Centos 6.2 now requires mysql-libs as a
dependency for postfix and cronie. When I try to install the mysql cluster
rpms from mysql.com I get a collision between the files.
Since this is the first time I get into contact with mysql cluster I wonder
if somebody has an idea how to resolve this or knows alternative packages
that don't conflict with mysql-libs?

Regards,
  Dennis
