Forum OpenACS Q&A: Tutorial Problems (converting XML to HTML)

I am trying to follow along with the tutorial(creating a new package called notes) but I encountered a problem. I was told to edit the "index.xml" file. I was supposed to run the make command but I get some errors. I did some reearch and I realized that I need doc-xsl or xsl-stylesheets folder which I have installed. I tried to run make again and this is the error I received
cp -u *.png ..
cd .. ; /usr/bin/xsltproc ../../../acs-core-docs/www/xml/openacs.xsl xml/index.xml
xmlNanoHTTPConnectAttempt: Connect attempt timed out.xmlNanoHTTPConnectAttempt: Connect attempt timed out.xml/index.xml:3: warning: failed to load external

I also need to download Docbook XML DTD and get xsltproc. How do I go about handling all that? Thank you James
