It would be nice if freetype obsoleted freetype2 and freetype-devel obsoleted freetype2-devel Ximian GNOME uses these subpackages with Red Hat Linux does not. I realize upgrading from a system with Ximian GNOME isn't supported, many users will do this, and it should work as well as possible.
We only support package upgrades from official Red Hat packages, that have been through our QA processes, etc. We do not support upgrading from externally supplied packages and cannot realistically track various random changes that external packagers may make.
