It looks like setup/build_environment.py detects it at *INC/podofo.h instead of *INC/podofo/podofo.h which is where podofo.h and its own include files expect to find itself.
Subsequent to this, calibre/src/calibre/utils/podofo/podofo.cpp must be reset to #include <podofo/podofo.h>. After this, it'll all Just Work. (*INC and *LIB dirs must be of course set to the podofo install directory/include and directory/lib before it will, but after that, it's gold.)
