Oracle likes to bury the pre-requisite files for installing Common Array Manager on Linux inside their documentation. This is particularly painful to hunt down when installing on a 64-bit server. To simplify things, I have made an RPM that will resolve all the dependencies for CAM 6.9. You can find it on GitHub at https://github.com/genebean/cam-prereqs. Pre-built RPMs are there too in the download section.
