		WARNING: Your local Fink installation does not seem to use unstable Fink

		         found or possible to install. In this case please configure Fink to
		         use unstable tree using:
		         
		             fink selfupdate-rsync
		             fink configure
		         
		         and after that update Fink:
		         
		             fink scanpackages
		             fink selfupdate
		             fink update-all
