This is only a problem for people with USE="cjk" enabled, but the Japanese patch for waimea really lives at: http://www.kasumi.sakura.ne.jp/~zoe/tdiary/patch/waimea-0.4.0-ja.patch and not: http://www.kasumi.sakura.ne.jp/~zoe/tdiary/patch/waimea-0.4.0-japanese.patch as the ebuild assumes.
Fixed. Thanks for the hint.
Pleasure. :)
actually that shouldnt have been fixed ... the author of the patch e-mailed me and said he would be moving it
*sigh* Much ado about nothing.
