I miss two installation steps: 1. The question for automatic/manual partitioning and more importantly 2. The formatting of newly made Linux Native partitions! This way, the packages can't be installed
The only automatic partitioning that Red Hat Linux has ever supported is that available under Workstation and Server installations, and that functionality is still available in release 6.1. As for not getting asked to partition newly created ext2 filesystems, this screen should indeed be in there. Right after the Disk Druid screen, you should get asked which partitions to format. Let me know what you are seeing and we can help to get you on the right path.
