I was not aware pango was separate from gst-plugin-base.  I would like
to use GstTextOverlay and GstTimeOverlay, which I had thought were
part of pango, but I may be mistaken on that.  I added
gst-plugins-base-textoverlay to local.conf which seemed to do the
trick, thanks!

Which file are you referring to?  libgstfsl-0.10.so?  In /usr/lib I
have libgstfsl-0.10.so.0 and libgstfsl-0.10.so.0.01.

I just switched to Dora using kernel 3.0.35-4.0.0-wandboard.
