I also have good hopes that the linker bug will be fixed by Apple in  
the next version of the Xcode tools. It's unfortunate that it costs  
$500/year to get access to beta versions of major new OS releases,  
because otherwise I could properly test earlier on and then the bugs  
could be fixed before the OS is released to the public (when 10.5 was  
initially released, there were also several problems). Beta versions  
of minor Xcode updates are fortunately available to everyone nowadays.

Thanks.

You're welcome. I've also updated the message on the website about the  
problems with 10.6. I had forgotten to change it once the real cause  
of the problems was discovered.
