Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.244.mcz
==================== Summary ====================
Name: VMMaker.oscog-eem.244
Author: eem
Time: 2 January 2013, 12:03:44.839 pm
UUID: c9625bb4-bc55-4b75-942c-084c12ea9648
Ancestors: VMMaker.oscog-eem.243
Restore Cogit wanting COGMTVM to be determined on
command line. Probably broke in VMMaker.oscog-eem.218
