With USE="-emacs" and /usr/bin/emacs symlinked to zile, configure will hang: checking for x86_64-pc-linux-gnu-gandalf... no checking for gandalf... no checking for autom4te... autom4te checking for emacs... /usr/bin/emacs checking if /usr/bin/emacs is XEmacs... Patch will follow.
Looks like this package won't build at all without GNU Emacs being present. Therefore, the emacs USE flag should be removed and the dependency on emacs made mandatory.
