Description of problem: The required package libbeagle-devel is not available on ppc64. So the package won't build.
(Summary updated) libbeagle is now available for ppc64 for some time. But beagle itself isn't.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Sounds like this is a feature request to get beagle working on PPC and not a bug.
