>Description:
Trying to build "htdocs" on my machine dies with this error message:

[xsltproc] layout.xml -> autolayout.xml
I/O error : Attempt to load network entity 
http://docbook.sourceforge.net/release/website/2.6.0/xsl/autolayout.xsl
warning: failed to load external entity 
"http://docbook.sourceforge.net/release/website/2.6.0/xsl/autolayout.xsl";
compilation error: file /src/NetBSD-current/htdocs/./share/xsl/autolayout.xsl 
line 9 element import
xsl:import : unable to load 
http://docbook.sourceforge.net/release/website/2.6.0/xsl/autolayout.xsl
*** Error code 5

The reason for that problem is that "xsltproc" is trying to open a file
called "/usr/pkg/etc/xml/catalog". But on my system that file is called
"/etc/pkg/xml/catalog" because "PKG_SYSCONFBASE" is set to "/etc/pkg".

I've tried to trace down the error. It is printed out by
xsltParseStylesheetImport() after calling a function provided by "libxml2".

I've tried to fix the "libxslt" and "libxml2" packages by adding the
missing "CONFIGURE_ARGS+= --sysconfig=${PKG_SYSCONFDIR:Q}" to the
"Makefile" but that didn't help.

>How-To-Repeat:
1.) Put "PKG_SYSCONFBASE= /etc/pkg" in "/etc/mk.conf".
2.) Build the "netbsd-www" package from scratch.
3.) Try to run "make" in "htdocs".

>Fix:
Creating a symlink "/usr/pkg/etc/xml" pointing to "/etc/pkg/xml" works
arround the problem.
