It builds with QMake too (but we all know how much fun that is). The 
CMake binary distribution from
     http://www.cmake.org/files/v2.4/cmake-2.4.6-Linux-i386.tar.gz
should work on SuSE 10.1, though.

You will also need Qt 4.2, and while that's also easy to install it's 
not the quickest compile in the world. It comes with SuSE 10.2 though.

I've had reports of a conflict with Freetype 1.x if installed where 
freetype/freetype.h from freetype1 is found instead of 
freetype2/freetype/freetype.h from freetype2, so if you build it and run 
into freetype issues, that'll be the problem.

Thanks. That seems pretty sane, and is the general way I was thinking of 
doing it in Scribus originally (before I jumped on board with PoDoFo). I 
just wasn't sure how to handle some of the specifics. If you're happy 
with how the form xobject approach works that's what I'm inclined to 
implement for PoDoFo.

Guys, how does
     PdfObject* PdfDocument::CopyPageAsForm(const PdfPage*)
sound? It'd deep copy all resources to the new document (renumbering 
indirect objects in the process), update references in the copied 
objects, and generate a form object for the copied page.
