Heigh ho.

I've got a couple of quick questions.

First, background: I have a multi-file, valid, well-formed Docbook 4.1 XML document.  (xmllint --noount --noent --valid tells me it's OK, at least). I have converted it into reasonable HTML using the default stylesheets, with a little customization done by stylesheet-knowers here at Ximian. All well and good.

My Task: I'm now being asked for a PDF. I have managed to build a sort-of-ugly PDF (some pages have all the text in a tiny column down one side, for example, there are no stylesheet images, and I'll definitely need to customize the variablelists because they give equal space to the term and its explanation, which is not what I want exactly in terms of output, etc. etc.).

My Problem:  I can't figure out what it was that I installed that made it work, so our stylesheet-knowing-person can't actually reproduce even that much.

I have xmlto 0.0.8-3 and the latest versions of tetex, tetex-dvips, passivetex, xmltex, and so forth.

My questions:
What packages are required for converting a Docbook XML file to a PDF file, since it works for me and not for anyone else?

Am I using the recommended procedure, or is there a tool other than xmlto that I should be using?

Why would a PDF appear so broken when the HTML didn't?  Just the page size? I can see how running out of space would make a <screen> entry look pretty broken.
