Compile failure: eggdbus

[Robert J. Hansen]

Eggdbus, like libzvt, is failing to compile.  The relevant bits from the build log seem to be:

:info:build In file included from ../../src/eggdbus/eggdbuserror.h:29,
:info:build                  from eggdbusbindingtool.c:26:
:info:build ../../src/eggdbus/eggdbustypes.h:31:38: error: eggdbus/eggdbusenumtypes.h: No such file or directory
:info:build In file included from ../../src/eggdbus/eggdbuserror.h:29,
:info:build                  from interface.c:27:
:info:build ../../src/eggdbus/eggdbustypes.h:31:38: error: eggdbus/eggdbusenumtypes.h: No such file or directory
:info:build make[3]: *** [eggdbus_binding_tool-eggdbusbindingtool.o] Error 1

Like with libzvt, there doesn't seem to be any useful information on how to mitigate this.  Does anyone have any suggestions?

And, for that matter, is it even possible to install GNOME on OS X with MacPorts, or are there a lot of other known problems that I'll be facing?
