This might be due to poor packaging upstream, since it's 'make install' doesn't install these files either, but... The header file "pdflib.hpp" which is what the documentation says to use for the C++ binding only exists in the bind/pdflib/cpp directory, and doesn't get copied to /usr/include. Strangely, the documentation also says to compile/link against pdflib.cpp directly, instead of making it a library. I assume this is to avoid trouble with C++ compile versioning issues. Maybe this .cpp file can get installed into /usr/share...?
I've added pdflib-7.0.4_p4 to the tree. Can you come up with a patch to it? I'll try to fix this but don't know when i can get to it.
Okay, found a way to do this. It will be in a -r2 (in the tree as soon as there's a solution to bug #253263)
Removed from main tree.
