Moving to Fedora Core 5 requires to rebuild all arch specific Fedora Extras packages. Accordingly build dates, this does not seem to have happened for this package. Please rebuild the package as soon as possible. When you did this already, ignore and close this bugreport please. For more information see http://www.fedoraproject.org/wiki/Extras/FC5Status.
The package doesn't currently rebuild on FC5 ppc. The problem has been reported, but no news so far : https://bugs.freedesktop.org/show_bug.cgi?id=6277
Well, I finally got around to rebuilding it, only to find out that it had been included in Core for a while already, *sigh*
