Also tried building the mobi with mobipocket creator, starting with the files in the expanded (from epub) OEBPS/content.opf which worked, except again no TOC even using mobipocket creator to build it. Or pointing the TOC guide entry to toc.ncx
From my past experience, MobiPocket Creator and Kindlegen ignore toc.ncx. The toc must be built into the book file and then marked in semantics.
