Neither of those XARs open on MacOS X because they contain PNGs and the file IO code has not yet been upgraded to byte swap PNGs (or that's the story, at least). I expect that the same will be seen on Linux PPC. This is Bug 929 "Failure reading PNG bitmap".

Are you willing to post a XAR with has neither a PNG nor a JPEG - the Mac will probably open it? I appreciate that the artwork shown here does need a background picture to work.
