Yaakov, As a result of the recent libpng update, emacs won't build. emacs-X11 depends on gdk-pixbuf, and the latter (in its *.pc file) requires libpng14. I manually changed libpng14 to libpng15 just to allow the build to complete, but I don't know what consequences that might have. Are you planning a gdk-pixbuf update in the near future? Thanks. Ken
