This package fails to build in mock if the minimal build group is reduced to only the packages listed in the Exceptions section of the packaging guidelines. build.log is attached. This problem can be fixed by adding buildreqs of intltool and pygtk2-libglade P.S. Have you considered %ghost-ing the .pyo files?
