it just tells us that you are running a binary distribution of Sage built by Karl. I suspect that the problem is that the package you're trying to install is a very old (from 2007) and since then OSX has changed much. And there is no regular testing of experimental packages, so you're more or less on your own here. By the way, are you sure you have XCode's command line tools installed? If yes, it might mean that you need to replace a call to ranlib to an equavalent call to ar: at least on Linux: "running ranlib is completely equivalent to executing ar -s" So you might edit the spkg-install script to fix it, or create a ranlib shell script that will call ar... Let us know if this works.
