Some SRCDIR != BUILDDIR problems are to be expected with GTK+
 A) We do generated file generation in srcdir because we
    distribute them.
 B) We have automake-1.4 workaround hacks
 C) GTK+'s build process exceeds the complexity that make can
    handle easily.
 D) Nobody tests it 

I _suspect_ that if you typed make again, things problem would
have worked. One thing that might help is makeing the 
rebuild-in-sourcedir rules more like the way Pango does
them (using 'GPATH'  ... see pango/pango/ But
that isn't very reloiable either.
When I have time (hah!) I plan on redoing all the generation rules in
the gdk/ gtk/ makefiles over with automake-1.6.
