If you are building packages in the same way as scallywag with:

	$ cygport PKG.cygport download all check

then to install all binary packages for dogfooding:

$ for tar in PKG-VER-1.ARCH/dist/PKG/**/*PKG*-VER.tar.*z*
	tar -x -C / -f $tar	# * -C / installs usr/... under /usr/

for example, I just did:

$ for tar in \
	tar -x -C / -f $tar
