Updating rubinius to the most recent version.
Updating rubinius to the most recent version.

The rubinius team yanked the rbx-2 binary.
I tried building with rbx-3 explicitly, since the latest
travis-canary[1] build suggests that this works, but that
didn't work either.

I contacted travis support, and they suggested trying
to build on a different distro (trusty), but I got the same
error.

At this point I think that if you're using rubinius in production
with the etsy gem, perhaps you can help figure out how to get this
working.

I give up.
