I added the waimea-0.5.0 prerelease to portage. The 0.4.0 cjk-patch does not apply to this version, and they seem to have made som changes as the Font.cc file is missing. In case a patch is still required for CJK support I would appreciate some help on the matter as I have no way of verifying this.
waimea-0.5.0 does not need any patch for CJK support. but unfortunately there are the crash bug on the environment that LANG not C. I had already sent a patch to fix this problem to the author of waimea. I also post here.
Created attachment 32903 [details, diff] patch
