Well someone build a mac vm a few weeks back and as far as I know...

	0.  Grab your 3.8.1 image, install Balloon 3D, and then install  
version 3.8b6 of VMMaker, from
	or later...

	When this loads rely yes to move FloatProto to Undeclared.
	Now load the following two change sets found in the  
specialChangeSets folder.
	Note these might be in the VMMaker update since this doc was  
written, check the change set and
	the image after loading VMMaker to see if you need these items.

	load VMM38-gc-instrument-image.1.cs
	load VMM38-64bit-imageUpdates.1.cs

	That should provide a version of VMMaker that is sufficient to build
