[opensuse] Evince & XPS? (on openSUSE 12.1)

I find references on the Evince roadmap that it can read XPS files since late 2011. This is done using functionality built on libgxps [a XPS related library]. But these files do not open on openSUSE 12.1 and I can't find a reference to a libgxps package [zypper search xps]. Is this support for a later version of Evince that is available for openSUSE 12.1? Or is libgxps not packaged for some reason [other than 'nobody has done it yet']? evince-3.2.1-2.1.2.x86_64 Linux linux-nysu.site 3.1.10-1.9-desktop #1 SMP PREEMPT Thu Apr 5 18:48:38 UTC 2012 (4a97ec8) x86_64 x86_64 x86_64 GNU/Linux
