porblem compiling avahi-app

[Robert Huff]

Hello:
	While trying to compile net/avahi-app updated to last night,
I get:

  CC     libavahi_gobject_la-ga-client-enumtypes.lo

  CC     libavahi_gobject_la-ga-enums-enumtypes.lo
  CCLD   libavahi-gobject.la
  GISCAN Avahi-0.6.gir

	Any idea what's broken?
	(The purpose here is to replace the dependency on libicu18n.38
with libicu18n.46.)

	Respectfully,
