Yoiks! You clearly need gSTLFilt. Please post such things as
attachments or in some other way that doesn't insert linebreaks.
After reconstructing your lines and 'filt-ing, I get:

So the problem is that you're trying to wrap PyActor in a way that
implies it is default-constructible. But it's not; it's an abstract
class. You need no_init. See
http://www.boost.org/doc/libs/1_37_0/libs/python/doc/tutorial/doc/html/python/exposing.html#python.constructors
