Building a local copy of www.freebsd.org

[Peter Jeremy]

I'm trying to build a local copy of the FreeBSD website so I can do some
experimenting and try to improve some of the things I don't like about
the new website.  Unfortunately, my attempt to build the website dies:

===> news/2000
/usr/bin/sed -e 's/<!ENTITY date[ \t]*"$Free[B]SD. .* \(.* .*\) .* .*
+$">/<!ENTITY date      "Last modified: \1">/'  index.sgml |  /usr/bin/env
+SGML_CATALOG_FILES=  /usr/local/bin/sgmlnorm -d  -c
+/usr/local/share/sgml/html/catalog -D /var/tmp/build/www/en/news/2000 >
+index.html ||  (/bin/rm -f index.html && false)
/usr/local/bin/tidy -i -m -raw -preserve -f /dev/null -asxml  index.html
*** Error code 1 (ignored)
===> news/2001
make: don't know how to make index.html. Stop
*** Error code 1 (ignored)
*** Error code 2

Stop in /var/tmp/build/www/en/news.

I've tried both following the instructions in
http://www.freebsd.org/doc/en_US.ISO8859-1/books/fdp-primer/the-website-build.html
as well as using www/tools/webupdate with the same result.

I presume the errors from "tidy" are expected but why can't I create
www/en/news/2001/index.html?
