You might try my ruby-packstruct (which lets you define
binary-accurate structures in Ruby, similar to but independent of
ruby/dl) library, and see if you can't do the shared memory interface
yourself. I don't know of any interfaces (haven't looked really) to
the shm functions themselves, but writing one if you're decent in C
shouldn't be hard at all.
