Comment 5 for bug 709517

Oh, of course. That makes sense.

One slight variation of what you propose would be to provide the extra path as a hint to cmd_runner.Popen(), which would first look for the utility there and if not found just move on and hope it's found somewhere in the $PATH. This way we don't have to mess with the environment, although it shouldn't be a problem as we should mess only with the environment of that single Popen invocation.
