mirroring www

[Dikshie]

hello,
I'm follow:
http://www.freebsd.org/doc/en_US.ISO8859-1/articles/hubs/mirror-howto.html
section mirroring the WWW pages.
but I got:
fileserver# make
"/usr/share/mk/bsd.subdir.mk", line 57: warning: duplicate script for target "_SUBDIR" ignored
"/usr/share/mk/bsd.subdir.mk", line 8: warning: duplicate script for target "files" ignored
"/usr/share/mk/bsd.subdir.mk", line 8: warning: duplicate script for target "includes" ignored
===> en
"/usr/www/en/../share/mk/web.site.mk", line 84: Could not find /usr/www/en/../../doc/share/mk/doc.common.mk
make: fatal errors encountered -- cannot continue
*** Error code 1

Stop in /usr/www.



any suggestions ?




thanks !
