I can't reproduce your problem with the system packages. (Although I can 
if I set LD_LIBRARY_PATH to a locally compiled Python shared library.) 
But I can't get the PyQt example working either (ie. the C++ plugin 
loads without error but it then doesn't load the Python plugins).

I'll wait for Scott to say if he thinks the standard Ubuntu packages 
should just work and if he had to do anything to make it so.
