hi,
My named is Arnaud Jean Baptiste, i work with VMMaker and, i have try to load VMMaker via Gofer on Pharo (severals versions of the image, rc, alpha, dev).
and then the :
when i load the VMMaker package gofer don't find any version and raise a exception.
The code:

	 addPackage: 'VMMaker';
	 load.

raise a unbound exception.
