inkscape-0.48.2 does not build

[Jan Henrik Sylvester]

I have trouble building inkscape-0.48.2 on 9.0-RC3/amd64 with all other 
ports up to date. I think the first error is:

extension/internal/wpg-input.cpp:58:44: error: 
libwpg/WPGStreamImplementation.h: No such file or directory

graphics/libwpg does not seem to provide that file. Or where is it 
supposed to come from?

Here is the full log:
