This has been dogging me for two weeks. First on my CentOS 6.3 cluster, on which I completely uninstalled and tried to re-install, and then most recently on my fresh CentOS 6.6 build. On the latter build I initially had a text only build, then installed Java before trying to install CM again. Always with the very same result.
