As far as I know Ruby/DL does not yet work properly on 64 bit platforms. 
The author plans to fix that, but didn't have the time to do it when I 
last contacted him.

I think this would involve changes in lots of places because Ruby/DL 
seems to be using one-byte type tokens and .pack() internally. However 
if you want to use the native bit-width of the system you will need to 
use "L_" instead of "L" and so on in the pack arguments. So I think this 
would involve changing the semantics in quite a few code locations...
