What version of SWIG are you using? I'm glad to see the progress  
you've made, but certainly previous versions of the Perl and Python  
wrappers uncovered various bugs with SWIG itself.

Good to know. It should be possible to inject this into the SWIG output.

Since the Ruby support in SWIG is relatively new and continually  
improving, I'd suggest grabbing the latest SWIG from CVS and giving  
that a spin first:
http://www.swig.org/cvs.html

If that doesn't work, let's submit this as a SWIG bug and see what  
happens. It's often hard for me to follow the SWIG auto-generated code.

As far as getting autoconf building working, I'll see if I can't get  
that working soon. It turns out that I was missing some packages.
