# General build stuff:
# automake, bison, flex, git, gnome-common, gtk-doc, intltool,
# libtool, pkgconfig
#
# Devel packages needed by gnome-shell and its deps:
# dbus-glib, gconf, GL, gnome-menus, gstreamer, gtk, libffi,
# libgnomeui, librsvg, libwnck, python, readline, spidermonkey
# ({mozilla,firefox,xulrunner}-js), xdamage
#
# Non-devel packages needed by gnome-shell and its deps:
# glxinfo, gstreamer-plugins-base, gstreamer-plugins-good,
# python, Xephyr, xeyes*, xlogo*, xterm*, zenity
#
# (*)ed packages are only needed because gnome-shell launches them
# when running in Xephyr mode, and we should probably change it to use
# less lame things.

# Can this be simplified? Obvious ways don't handle handle packages
# that have been installed then removed. ('purged' status, e.g.)
