But again, if you are missing parts of dpkg and libc-bin your install is horribly borked. We have no idea what else is broken or how it got that way (FrankenDebian, anyone?), so there's no guarantee any advice given here will actually work.
Your best option is to reinstall the OS. Failing that, ignore this viber thing for a minute and concentrate on fixing the bigger problem. Then, when the rest of the system is in a predictable not-borked state, installing viber will go smoothly.
A good start would be to figure out
how broken this install is.
Have you checked if ldconfig and start-stop-daemon exist in /sbin/?
What's in your sources.list, and what does 'echo $PATH' say when run as root?
Once is happenstance. Twice is coincidence. Three times is enemy action. Four times is Official GNOME Policy.
