I guess for wheezy this would mean that it should be removed from s390x,
given that this package does seem to be maintained through NMUs and hence
there's probably no one who would go and forward and/or debug this.
I didn't find any patches over in the RPM world at first glance, but then
I utterly failed to find any SRPMs anyway.
Kind regards
Philipp Kern
