I think you identified the problem correctly. Have you read
http://www.rasterbar.com/products/luabind/docs.html#smart-pointers ?
You need to specify ofPtr as an template argument when registering your class and make sure
that a get_pointer() function is available in the same namespace as ofPtr (global is only
sufficient if ofPtr is itself global).

boost::shared_ptr? Then just specify ofPtr as template argument, as said above, and you
should be done.
If not, you additionally need to supply an appropriate get_pointer() function. For
std::shared_ptr, you can use a header I made for this purpose (just include it):

I hope I could help,
