[glade--]doxygen reference for libglademm

[joe@cs5 libglademm-2.0.1]$ cd docs/reference
[joe@cs5 reference]$ make
doxygen Doxyfile
Error: tag INPUT: input source `@LIBGNOMEUIMM_DOXYGEN_INPUT@' does not exist
make: *** [libgnomeuimm-reference] Error 1

I'm trying to build the doxygen documentation for libglademm (since I can't
seem to find it anywhere) and I'm getting the above errors when building it.  

(I guess I'm building it wrong?)

Thanks,
Joe
