You don't show the full class above, do you have the "= 0" at the end of 
the declaration for the Clone method?  If so then SWIG is going to 
recognize it as a pure virtual method and will not let you create 
instances of it.  (Since I had my own style of dealing with ABCs before 
SWIG was smart enough to deal with them itself, I always leave out the 
"= 0"'s and just comment out the constructor declaration myself.  It 
accomplishes the same thing.
