Your current Emacs version does not support running as a daemon which
is required for ${CATEGORY}/${PN}.
Use "eselect emacs" to select an Emacs version >= 23.
EOF
elif [[ ${has_gtk} == t ]]; then
while read line; do ewarn "${line}"; done <<-EOF
Your current Emacs is compiled with GTK+. There is a long-standing bug
in GTK+ that prevents Emacs from recovering from X disconnects:
<https://bugzilla.gnome.org/show_bug.cgi?id=85715>
If you run Emacs as a daemon, then it is strongly recommended that you
compile it with the Lucid or the Motif toolkit instead, i.e. with
USE="athena Xaw3d -gtk -motif" or USE="motif -gtk -athena -Xaw3d".
