You must be using some old version of GStreamer, or at least an old
version of gstconfig.h (I think ossbuild mixes them up a bit, not sure
why). QtGStreamer makes no use of the deprecated XML APIs of GStreamer
and is compiled with -DGST_DISABLE_XML -DGST_DISABLE_LOADSAVE, which
effectively turn off the inclusion of libxml headers and remove this
extra dependency on libxml. The relevant section in gst/gstconfig.h,
in recent versions of GStreamer reads:

    198 #ifndef GST_DISABLE_XML
    199 #ifndef GST_DISABLE_DEPRECATED
    200 # include <libxml/parser.h>
    201 #endif
    202 #else
    203   /* FIXME: 0.11 (replace by GST_DISABLE_XML) */
    204 # define GST_DISABLE_LOADSAVE_REGISTRY
    205 #endif

So, make sure your copy of GStreamer and/or gstconfig.h is up-to-date
and try again.
