Wrox Press also give you the code for that Book for download on their website. The Solution for the Minimal Site Definition you'll be lookng for lives in Chapter 5. But beware, there are a few bugs in the download. Check the Errata for Errors in Download and fix up the onet.xml and publishing layout page.
One thing that was missed totallly in this definition is the fact that all pages should live in the Pages Library. Also the homepage. In the example from Andrew, the home page lives WSS style in the Root. Not very clean. The fix is simple enough though: Change the url of the page (preferably even changing the default.aspx to actually use the layout properly!) and you're ready to go. Here is my version of the last entry in the onet.xml file:
<Module Name="Default" Url="" Path="">
<File Url="default.aspx" NavBarHome="True" Type="Ghostable" />
<Module Name="Default" Url="$Resources:cmscore,List_Pages_UrlName;" Path="">
<File Url="Default.aspx" Type="GhostableInLibrary">
<Property Name="PublishingPageLayout" Value="~SiteCollection/_catalogs/masterpage/PSATOC.aspx, ~SiteCollection/_catalogs/masterpage/PSATOC.aspx" />
<Property Name="ContentType" Value="$Resources:cmscore,contenttype_welcomepage_name;" />
