The gstreamer postinstall scriptlet fails during installation: 
   2:gstreamer             
########################################### [ 40%]
error: %post(gstreamer-0.7.3-3) scriptlet failed, exit status 127

% rpm -q gstreamer
gstreamer-0.7.3-3

% rpm -q --scripts gstreamer
postinstall scriptlet (using /bin/sh):
/sbin/ldconfig
env DISPLAY= /usr/bin/gst-register --gst-mask=0 > /dev/null 2> /dev/null
postuninstall program: /sbin/ldconfig

The postinstall scriptlet looks strange.  gst-register is actually
installed as "gst-register-0.7" and the argument has changed.

I believe the following works:
  /usr/bin/gst-register-0.7 --gst-plugin-spew
