I believe the project's supporting files for other formats aren't complete ... I also ran into the texinfo => tex => PDF version having title page & other errors in the rendering steps - but saw that the ASCII version "make c.txt > text.txt" generated the indexes / cross-references. I think the build environment will be likely getting several enhancements to render correctly.
