Alas 10.6.8 is now unsupported.  The new VMs only run on 10.7 or later.
This is not a superficial change.  We have moved the platform subsystem to
Cocoa (Objective-C) from Carbon (C), necessitated by providing 64-bit
support.  It would be a lot of work to produce an up-to-date 32-bit Mac OS
X VM for 10.6.8.  Sorry :-(
