In kooka 3.4.0 if I select gocr recognition method and try to use it I always get ocrad not found. It's a bug posted to bugs.kde.org (90082) http://bugs.kde.org/show_bug.cgi?id=90082. I've made a patch for kooka's ebuild from that bug post. Hope it's useful and in portage soon! :D
Created attachment 58992 [details, diff] Patch to solve gocr problem in kooka This fixes kooka to accept and really use gocr as OCR engine.
Created attachment 58993 [details] new kooka-3.4.0 ebuilt to use the patch New ebuild to patch kooka src files with attached patch.
I planned to have this included in the 3.4.1 ebuilds, but quite forgot. I added the patch to the ebuild now.
