The rank function is broken -- it complains that the function lorder
is unbound. To fix it, if you are compiling from the sources change
the last line in stats.lsp from

(defun rank (x) (xlisp::make-compound x (lorder (lorder x))))

to

(defun rank (x) (xlisp::make-compound x (order (order x))))

On the mac or windows versions, the easiest fix is to

	Make a backup copy of xlisp.wks -- just to be safe

	Then in xlispstat do

		(defun rank (x) (xlisp::make-compound x (order (order x))))
		(save-workspace "xlisp.wks")

	Copy the new workspace to the startup direcory if it isn't
	already there.
