I would go with the approach of using the native C interface (ruby.h) 
from D. Perhaps add some wrappers to make the library simpler to use.

I'm not sure about the garbage collector, if it's a good idea to use it 
or not. Note that anything that you return to the Ruby code would most 
likely need to be allocated using some functionality of ruby.h, to 
allocate the memory on the Ruby heap and not the D heap.
