	##Issues:
	# - dfusion is strange. It's always been that, though.
	# - prebuilt ruby
	# - bundled lua
	# - isoworld requires agui
	# - prebuilt allegro for stonesense.
	# - stonesense conf file: /usr/share/games/dfhack-9999/stonesense/init.txt
	# Set in ./Config.cpp, installed together with the rest of the directory.
	# - output files
	# - - Make symlinks to (unversioned) /var

	# Doesn't build:
