That error has nothing to do with boost python. Apparently you did not link against the definition for the class Rectangle. You need to link against the object file generated from the definiton of Rectangle, usually you would have a Rectangle.cpp and generate a Rectangle.o. Your python module needs to link against Rectangle.o.
