says

build/linux-i386/clutter/types.xml
tmpfile.c:2:36: error: clutter/json/json-glib.h: No such file or directory
tmpfile.c:3:39: error: clutter/json/json-marshal.h: No such file or directory

Since 1.5.2, clutter doesn't ship these headers, it appears they should come with glib.
Debian removed them much earlier: 0.8.0 had them, but the current 1.2.12 not. So,
the attached patch tests for clutter 1.2.

Btw. thanks a million for LuaGnome!
And greetings from piefkeland :)
