No, you don't need Red Carpet. You can download the individual packages from here if you want to build it manually:
www.linuxpackages.net or you can make it easy on yourself and install the latest verison of Dropline, which you can get here:
www.dropline.net/gnome/
Personally, I am a huge fan of Dropline, and the latest version includes Evolution v1.4 as part of the default installation. Very Sweet!! Basically, Dropline will automatiacally install a large number (> 160) of common packages and other goodies, and I have found it to be invaluable in taking my rig to the next level. Note that Dropline will set your default window manager to Gnome, but if you prefer another, it's easy to set it back to your preferred choice. Overall it's pretty easy, and I'd recommend you give it a shot. -- J.W.
