I checked and I have a number of gstreamer pkg-config files:

        /usr/lib/pkgconfig/gstreamer-0.10.pc
        /usr/lib/pkgconfig/gstreamer-base-0.10.pc
        /usr/lib/pkgconfig/gstreamer-check-0.10.pc
        /usr/lib/pkgconfig/gstreamer-controller-0.10.pc
        /usr/lib/pkgconfig/gstreamer-dataprotocol-0.10.pc
        /usr/lib/pkgconfig/gstreamer-net-0.10.pc

but configure is looking for some I don't have:

        configure:20784: $PKG_CONFIG --exists --print-errors "gstreamer-0.10 >= 
$GSTREAMER_REQUIRED_VERSION
                             gstreamer-app-0.10
                             gstreamer-base-0.10
                             gstreamer-interfaces-0.10
                             gstreamer-pbutils-0.10
                             gstreamer-plugins-base-0.10 >= 
$GSTREAMER_PLUGINS_BASE_REQUIRED_VERSION
                             gstreamer-video-0.10"

As a result, GSTREAMER_CFLAGS etc. is empty.

The default in configure.ac is that video is enabled, and it doesn't
seem like it gets disabled if pkg-config cannot find all the right
packages:

        # check if gstreamer is available
        if test "$enable_video" = "yes"; then
           PKG_CHECK_MODULES([GSTREAMER],
                             [gstreamer-0.10 >= $GSTREAMER_REQUIRED_VERSION
                             gstreamer-app-0.10
                             gstreamer-base-0.10
                             gstreamer-interfaces-0.10
                             gstreamer-pbutils-0.10
                             gstreamer-plugins-base-0.10 >= 
$GSTREAMER_PLUGINS_BASE_REQUIRED_VERSION
                             gstreamer-video-0.10],
                             [have_gstreamer=yes],
                             [have_gstreamer=no])
        
           AC_SUBST([GSTREAMER_CFLAGS])
           AC_SUBST([GSTREAMER_LIBS])
        fi

I'll try to look into this more this afternoon/tonight.  Until then I
wouldn't bother doing too much work on it.  Let me try to reproduce your
results then we can see where we are.
