configure: error: You seem to be running X, but no X development libraries were found. You should install the relevant development files for X and for the toolkit you want, such as Gtk+, Lesstif or Motif. Also make sure you have development files for image handling, i.e. tiff, gif, jpeg, png and xpm. If you are sure you want Emacs compiled without X window support, pass --without-x to configure. 看网上说是需要安装 x 的 dev 库，但是不知道 redhat 能通过什么途径安装这个
