I found the problem. At bottom of this email are some ideas to fix it. 
Please suggest which one is best ...

So I looked in my old email from April 2006 and see I had same problem 
last year.

My workaround was:

mkdir /home/reed/pkg/etc/xml
ln -s /home/reed/etc/xml/catalog /home/reed/pkg/etc/xml/catalog

And now it builds fine.

My problem is I use PKG_SYSCONFBASE=/home/reed/etc, but something is using 
hard-coded ${PREFIX}/etc/xml/catalog.

Looking farther in my mail, I see another workaround is to set 
PKG_SYSCONFBASE=/home/reed/etc on my bmake line.

The htdocs/share/mk/web.site.mk checks for PKG_SYSCONFBASE not 
PKG_SYSCONFDIR.

MAKE_ENV doesn't have that. It has:
PKG_SYSCONFDIR=/home/reed/etc

According to documentation: Packages must not use PKG_SYSCONFBASE 
directly. (Although I see some do.)

Anyways I remove the symlink above and here is my other work-around:

 do-build:
 .for _output_ in ${OUTPUTS}
-       @cd ${WRKSRC} && ${SETENV} ${MAKE_ENV} ${MAKE_PROGRAM} ${MAKE_FLAGS} ${_output_}
+       @cd ${WRKSRC} && ${SETENV} ${MAKE_ENV} PKG_SYSCONFBASE=${PKG_SYSCONFBASE} ${MAKE_PROGRAM} ${MAKE_FLAGS} ${_output_}
 .endfor


Should htdocs/share/mk/web.site.mk be fixed to check for PKG_SYSCONFDIR?

Should MAKE_ENV just include PKG_SYSCONFBASE?

Should we include as a "build" dependency the xmlcatmgr buildlink3.mk and 
modify htdocs/share/mk/web.site.mk to also use the XML_DEFAULT_CATALOG 
defined there?

Or should I just commit this patch for doc/guide/Makefile above?
