I can see there is some reasoning in adding X protos to RDEPEND of x11-libs/ but not for x11-apps/ (due to limitations of Portage) And libXt is not linked against, only headers are used Please avoid spreading this to more x11-apps/ Thanks!
And you propably want to recheck everything, from quick look. xwd.c:#include <X11/extensions/XKBbells.h> ssuominen@null /tmp/xwd-1.0.5 $ qfile -v XKBbells.h x11-libs/libxkbfile-1.0.8 (/usr/include/X11/extensions/XKBbells.h)
Fixed, thanks!
