Portage contains wesnoth-1.8.5 which is masked for PPC achitecture. Version 1.8.4 is OK (at least it was before I synchronised portage). Please leave older versions in portage as long as they are not unmasked for all architectures.
Steps To Reproduce: emerge --update wesnoth

ssuominen, I'll assign it to you because you were the one who removed it :P
Removed in purpose because of long bug queue ppc* arch's have. It's just a game, afterall, just add it to your package.keywords.
