build failure for net/avahi

[Paul Goyette <paul%whooppee.com@localhost>]

With pkgsrc updated to just a couple hours ago, I'm getting the 
following failure for net/avahi

	...
	checking for GOBJECT... yes
	checking for gobject-introspection... yes
	checking for QT3... no
	configure: error: Package requirements ( qt-mt >= 3.0.0 ) were not met:

	Package 'qt-mt', required by 'virtual:world', not found

	Consider adjusting the PKG_CONFIG_PATH environment variable if you
	installed software in a non-standard prefix.

	Alternatively, you may set the environment variables QT3_CFLAGS
	and QT3_LIBS to avoid the need to call pkg-config.
	See the pkg-config man page for more details.
	*** Error code 1

This is with

	...
	The currently selected options are:

        	gtk2 introspection
	...
