	# $INC{inc/Module/Install.pm} is what will still get set as long as
	# the caller loaded module this in the documented manner.
	# If not set, the caller may NOT have loaded the bundled version, and thus
	# they may not have a MI version that works with the Makefile.PL. This would
	# result in false errors or unexpected behaviour. And we don't want that.

Please invoke ${\__PACKAGE__} with:

not:

	use ${\__PACKAGE__};

Your installer $0 has a modification time in the future ($s > $t).

This is known to create infinite loops in make.

Please correct this, then run $0 again.
