It would be nice if we didn't have to actually try to execute ruby. But it's probably the most foolproof check.

Should we print a warning?

Should the prettypatch module do something sensible when ruby isn't installed, too?

Same question.

Yeah, I don't know of a better way to do this.

I don't think we generally want to print warnings when we skip over tests that we know we can't execute, just like we don't in run-webkit-tests. 

At some point when I can revamp test-webkitpy it'll have more useful logging for this sort of thing (bug 49299)

Maybe. I'll file a separate bug to look into that. Right now this is trapped in new-run-webkit-tests, but I think webkitpy.tool will probably get upset.
