Welcome to RPM dependencies.
One thing that really helps is a tool called apt4rpm,
link, which will automatically download and install the dependencies for you. For instance, if you were using it to install gaim, you would type on the command line, "apt-get install gaim", and it would install libao and whatever else may be needed. I realize that you may not be very good with command-line tools yet, but trust me, it's definitely worth it.
