I set LD_LIBRARY_PATH at build time.  Big improvement.  However, I am still

Could not write method GstStructure.get_uint: No ArgType for 'guint*'

followed by many more "Could not write method ..." and "Could not write
function ..." messages.  I also set LD_LIBRARY_PATH in the shell from which
I ran the program.  I was able to import gst, but I got the message:

AttributeError: 'module' object has no attribute 'Element'

The gst version is 0.10.23 and the pygst version is 0.10.15 -- both good, so
I must be close.

So, do I actually need to build the gio plugin?
