I have scoured the net looking for answers and have found none.  Not even on the site for chipmunk-ffi itself on github, which I find rather strange...

Regardless, my question is how do I get chipmunk-ffi working with ruby? I see that it's looking for a file, but what file would that be? Some sort of chipmunk executable I would presume, but where is that stored?

I had been all about using the standard chipmunk gem which seems a lot more straightforward from my perspective until I learned that certain features are missing.  So I though I'd at least take a look at the competition.  Also, apparently the C extension version doesn't work on MacRuby, and I'm starting to think that is a better means of deploying my open-source game on OSX than having my users install the latest version of ruby through MacPorts.
