[Inkscape-devel] Doxygen Documentation

Hello devs, I've built my local copy of Inkscape's doxygen documentation. My documentation does not have class diagrams. Is this consistent with other people that build it for the 0.49 development branch ?

I found the 'unofficial' doxygen documentation for the Inkscape-0.48. http://fossies.org/dox/inkscape-0.48.4/structSPDesktop.html

You can clearly see the class diagram in the link. My local copy doesn't build those. Any thing I am missing ?
