It had me stumped for awhile. Compiling 'cups-filters' failed, reported missing "gdbus-codegen". At first I thought it had something to do with dbus package.

Finally found that 'gdbus-codegen.py' is missing from package 'glib'. This is caused by a patch applied to glib: 'glib-no_python.patch'. I removed that patch and was able to compile cups-filters.
