Subject: ruby vtk bindings

I'm wanting to use ruby with VTK (http://public.kitware.com/VTK/). 
Currently I'm getting errors compiling the ruby bindings 
(http://www.gfd-dennou.org/arch/ruby/products/ruby-vtk/):

g++ -fPIC -Wall -g -O2  -fPIC   -I. -I/usr/lib/ruby/1.8/i486-linux 
-I/usr/lib/ruby/1.8/i486-linux -I. -DHAVE_VTKCONFIGURE_H 
-I/usr/include/vtk  -c vtkTk.cxx

make: *** [vtkTk.o] Error 1

The big mess of warnings is also somewhat worrisome, but I'd just like 
it to compile first. I'm running Ubuntu (Breezy) with all the latest 
updates. I installed vtk and tk through apt. I also made sure tk.h was 
on my system:
$ find /usr/include -name tk.h
/usr/include/tcl8.4/tk-private/generic/tk.h
/usr/include/tcl8.4/tk.h

I don't have much experience compiling my own libraries from scratch so 
I'm not quite sure what I'm doing wrong.

Also it seems the ruby bindings are somewhat old and not much is 
happening with them. Is there a gem out there or better documentation?

Thanks for the help!
