I never said you would :)

" If you open extension/init.cpp and search for
" CairoRendererPdfOutput and CairoRendererOutput you
" can activate Save as "Cairo PDF experimental"
" and "Cairo PNG"

Simply change the "if (0)" into "if (1)" and recompile. That should activate the two extra export formats.

Again, I think you should search for a much simpler example. Try a drawing with only two or three objects. When does clipping/masking work and when doesn't it? Post both input svg and output pdf (don't bother with ps or printing yet). Only then can you hope for Adrian to tell whether Inkscape or Cairo is wrong :-)
