That may be true if you're using GNS. There hasn't been a new Dynamips or Dynagen build for some time, so the repo packages for those are "up to date." The Dynagen repo build is 0.11.0, and the Dynamips is 0.2.8-RC2.
GNS is nifty for the integration with PEMU/QEMU and vBox, but if you're just trying to make the Cisco stuff work, explore Dynagen without the GNS UI. There's a bit of a learning curve but once I decided to figure it out it only took an evening to get going with it from the CLI.
