I don't know what version is included with fedora core 5, but i strongly recommend that you stick up to it, why? because it will work without problems and extra configuration.
However, if you are an adventure guy like me you can always compile the source and enjoy maximum performance.
Make shure you have a standard development environment:
gcc
development packages for libgtk
development packages for libgtk2
pkgconfig
make
