can't build gimp-help-en due to missing Sourceforge file

[Robert Huff]

	[I sent mail to the maintainer (cc'ed: here) but had no
respeonse.  And there's nothing about it in UPDATING.  So ...]


	While attempting to update to the latest version I get:

Copying images (en) ... 1605
*** Making html for en ... 
I/O error : Attempt to load network entity http://docbook.sourceforge.net/release/xsl/current/xhtml/chunk.xsl
warning: failed to load external entity "http://docbook.sourceforge.net/release/xsl/current/xhtml/chunk.xsl"
compilation error: file stylesheets/plainhtml.xsl line 10 element import
xsl:import : unable to load http://docbook.sourceforge.net/release/xsl/current/xhtml/chunk.xsl
gmake[1]: *** [html/en/index.html] Error 5

	Is there something I've failed to update, or even install?
	What's up, and how does it get fixed?

	Respectfully,
