Subject: C++ extensions, garbage collection, Ruby and SWIG

I wanted to use SWIG to make a Ruby extension out of an existing C++ 
library (http://www.itu.dk/research/buddy/index.html).  When it comes to 
extensions and GC I've seen exhortations like the following on the list:

"Be sure to understand ruby's memory management before attempting to 
design your classes. Since you want to write a "C++ extension to Ruby", 
you should defer all memory management to the ruby interpreter."
 - Tobias Peters

That actually sounds like good advice, however the library I want to 
'swig' already has 'automated garbage collection' as a feature.  Will this 
cause trouble?  Are there ways to work around the problems that might 
be caused by this?
