As posted to bug 250723, this makes the libkate dependancy optional and selectable with a USE flag.
Created attachment 182602 [details, diff] Patch to disable automagic libkate dependancy The attached patch disables automagic libkate dep. and instead listens to the argument libkate=(yes|no). Note that I didn't use the more standard "with-libkate" or "enable-withkate" syntax as the scons option parsing doesn't like hyphons.
Created attachment 182603 [details] New ebuild using attached patch An updated ebuild making use of the attached patch to remove automagic libkate dependancy (and depend instead only on kate use-flag). Note that this ebuild also has the fix from 255887 included.
