Sadly -c/-noruntime option was removed some time ago, only thing that's 
left from those good times is
'swig -ruby -external-runtime', which sadly isn't very helpful.
I even thought about writing some preprocessor script to remove most of 
the runtime from .cpp files and
writing a glue for generated files but doing it right would require a 
bit of time, which is unobtainable at the moment.
