One of the easy ways to get GAIM is to install synaptic and it will take care of all the dependencies that are necessary for the prog operation. And to get synaptic as root type:
yum install synaptic
yum is a program that comes with FC2, synaptic will be accessible from your menu window in systems setting i think.
I hope that helps, plus with synaptic you have access to lots of softwares and tools you might need.
