I think the website has you confused, while the Intel port had the latest updates, the PowerPC version has not been updated since 2002. (The readme was written in 2012)I have the original cd + the mac os x launcher but the file I mention contained all the latest updates ported to mac os x.
None of the macintosh Garden site does, sadly
All the bugs in the original port are still documented in the readme for the version from Unrealism. The only advantage to that particular download is that it helps walk you through modifying your ini for your specific resolution.
