cheese-2.32.0 fails to build under Slackware64-13.1

I'm having problems building cheese-2.32.0, it fails while compiling 'cheese-camera.c'. Here is make output:

make[3]: Entering directory `/home/witchdoc/Stuph/Software/Source/Slackware_scripted/Video/cheese/cheese-2.32.0/libcheese'

I don't know the works of GStreamer, but as it appears to me 'cheese_camera_cat' is defined at line 137 in 'cheese-camera.c':

GST_DEBUG_CATEGORY (cheese_camera_cat);
#define GST_CAT_DEFAULT cheese_camera_cat

so, I'm not quite sure what's going on.
Installed gcc is 'gcc-4.4.4_multilib-x86_64-1alien' and GStreamer is 'gstreamer-0.10.29-x86_64-1' along with 'gst-plugins-base-0.10.29-x86_64-1', 'gst-plugins-good-0.10.22-x86_64-1' and 'gst-ffmpeg-0.10.10-x86_64-2gsb'.

I googled around a bit, but haven't been able to find solution.

Help?
