Now Squeak trunk is using Context too the compatibility package isn't needed.  I've updated the load script to eliminate CogCompatibility.st as you two both did.  That's pushed to github.  I'm also committing versions of VMMaker and Cog that no longer use the deprecated includedSubString:, so the builds should work less noisily now.

I assure you that it does work in the vm and in a Squeak image :-). I depend on this tool when analyzing vm performance.  I hope to fix the vm download script and hence the image build scripts today (but am busy this morning) so it should be easier to test.  IIRC it is loaded into the script-built VMMaker image so you could try it there.  Don't hesitate to contact me for operating instructions.  I'm on Skype.  Clément has my contact info.
