syntax highlighting doesn't work, nor throws errors.

I'm following the instructions here to make syntax highlighting work, 
are these the wrong instructions to follow?

http://www.sagehill.net/docbookxsl/SyntaxHighlighting.html

java -cp 
"/www/notlive/docbook/docbook-xsl-1.74.3-pre/extensions/saxon65.jar:/www/notlive/docbook/saxondamnit/saxon.jar:/www/notlive/docbook/xslthldamnit/xslthl-2.0.1.jar" 
\
-Dhighlight.source=1 \
-Dxslthl.config="file:///www/notlive/docbook/xslthldamnit/highlighters/xslthl-config.xml" 
\
com.icl.saxon.StyleSheet ./text.xml 
/www/notlive/docbook/docbook-xsl-1.74.3-pre/html/chunkohp.xsl

I've also tried without the "saxon65.jar" in there. also the 
-Dhighlight.source=1 \ was a recent attempt to get it to work, so I've 
tried without that too.

here's my text.xml file:

<programlisting language="php"><![CDATA[
function dostuff($now=false) {
                 if ($this->redo && !$force) return;
                 $this->redo=true;
                 foreach ($this->abas $r=> $a) {
                         $a->dostuff($force);
                 }

         }

                                 ]]></programlisting>
                         </sect1>
                 </chapter>
         </part>
</book>

My chunkohp.xsl file is the same as chunk.xsl except I added

<xsl:param name="highlight.source" select="1"/>
after
<xsl:import href="chunk-common.xsl"/>

I get html output with no syntax highlighting. Saxon 6.5.5.
