Is there something like synaptic or apt-get for 64bit?

I'm trying to upgrade my kde to 3.3 from the version that came on the CD. As I start getting into it, I'm noticing the inevitable missing dependencies. As I download them I find I need more and more. Synaptic used to take care of this on the 32bit version but I guess it doesn't work on the 64bit version. Is there anythng that WILL work? This dependency thing is killing me.
