just a small glitch: yelp-2.2.0 depends on >=libgtkhtml-2.1.2, but it should rather be =libgtkhtml-2.1* (or similar), since we also have libgtkhtml-3.0.x (evolution-1.3* dep) in portage, and yelp doesn't compile when only 3.0.x version is installed. best regards, artb.
thanks for the report. i've just updated the deps as you suggested (and also for the other yelp versions available.
