The features I'd like to use from the library are the macros
SWIG_SHARED_PTR and SWIG_SHARED_PTR_DERIVED.

I'm using swig-1.3.40 (standard for ubuntu 10.04).  The macros were
added in swig-1.3.34 (Feb 2008).  In the current version (swig-2.02)
they still work but are deprecated and replaced by %shared_ptr.

If they are available in SWIG 1.3.34, then we should be fine supporting it. I still have to make sure there isn't something else in the way Eric implemented it. I'm guessing you are right, though, and that when Eric started using SWIG this way, they did not natively support shared pointers. Hopefully, we can just move over to using the SWIG version without a problem and then you can have access to what you need.

Don't worry about the deprecation in version 2 of SWIG; I doubt we'll be moving there any time soon for compatibility reasons.
