Please add .desktop file for himerge to appear in gnome/kde menu. Thanks
himerge indirectly depended on xulrunner-1.8 which is no longer available in portage. see bug #282162 gtk2hs which himerge also depended on does not support the new xulrunner-1.8, and the gtk2hs team suggests to move to webkit instead. As a consequence himerge has been removed from portage, thus this bug has to be closed.
