OpenSSL patch instructions bug?

["Brian Szymanski" <bks10@cornell.edu>]

Hi. When I follow the directions for remaking libssl,
  make -f Makefile.bsd-wrapper obj
goes fine, but:
  make -f Makefile.bsd-wrapper cleandir
fails with the following error:
  make: don't know how to make clean. Stop in /usr/src/lib/libssl/obj.
  *** Error code 2
  Stop in /usr/src/lib/libssl2 (line 710 of
  /usr/src/lib/libssl2/Makefile.bsd-wrapper).

Am I the only one experiencing this problem? The workaround I used to get
libssl compiled was as follows:
	rm -fr /usr/obj/lib/libssl
	cd lib/libssl
	make -f Makefile.bsd-wrapper obj
+	echo clean: >obj/Makefile
	make -f Makefile.bsd-wrapper cleandir
+	rm -f obj/Makefile
	make -f Makefile.bsd-wrapper prereq
	make -f Makefile.bsd-wrapper includes
	make -f Makefile.bsd-wrapper
	make -f Makefile.bsd-wrapper install
