This is about the X server. When you build the plugins you had the x
server files present, but in your run time environment they are missing.
Just do an
ldd /usr/lib/gstreamer-0.10/libgstxvimagesink.so
it should be able to resolve all shared library. Also check your
/etc/ld.so.conf and LD_LIBRARY_PATH. Locate your x library and make sure
they can be found.
