Sorry for bumping this old topic, but I am having the same trouble. I successfully copied it over to /usr/bin, but when I execute it it claims that it is not found. (even when I am in the same directory that it is in). I find this to be rather odd. I also tried ./helomoto, and I get a permission denied, even as sudo gainroot. But I don't think that that is how I am supposed to execute it anyway. Any help would be grand, thanks!
