Issues building in Windows (MikTex)

[fazl]

Trying to build from latex source, on windows, using miktex-portable-2.9.6753 (selfcontained supposedly).
First I was getting errors about hevea.sty being missing, so I downloaded it from http://hevea.inria.fr/ into the book's top level folder (er, plus a few copies in the miktex tree, shotgun approach, having forgotten most of what I ever knew about LaTeX). That seems to have fixed the hevea issue.

Now I'm seeing this:

! LaTeX Error: File `latexonly.tex' not found.

I'm guessing you need to commit/push this and possibly other supporting files from your own local build tree ?

Or, if there is an obvious mistake I'm making, I'd appreciate anyone pointing that out. A cursory search in the web didn't help.

TIA, Fazl
