Quick update after poking around in the dl folder in ruby/lib.

DL::Importable is gone.  Use DL::Importer instead.

You can't pass nil into methods, I had to use DL::TYPE_VOID (something 
like that, can't remember exact syntax off top of my head).

I had to change a few things to CPtr, which I assume is new, to get them 
to work.

In conclusion if you have any dl code written for Ruby 1.8 - update to 
DL::Importer and you should be able to fix the rest using the error 
messages.
