	# hslibs packages. Exposing util breaks lots of things. Fortunately cabal
	# doesn't actually use anything fro util so we can remove it. A patch has
	# been sent upstream so remove this hack on the next cabal iteration.
	# Update: Seems that solving this upstream causes problems on Windows, so
	# this hack will remain for now.
