If you want to build the VM from the latest sources in Subversion,
then you *must* use the source code in VMMaker.

Use a Monticello browser to load package VMMaker from www.squeaksource.com.

On Squeak, you can load update-dtl.6.mcm with Monticello to load
VMMaker with other required packages. Once loaded, evaluate
"VMMaker updateFromServer" to ensure that you have the latest
versions.

Open a VMMaker tool (world --> open... --> VMMaker). The "Help"
button on the upper left of the VMMaker window provides additional
instructions.

If you are using Pharo, you can load VMMaker with ConfigurationOfVMMaker
(but be sure to use whatever Metacello command gives you the latest
version of VMMaker, not an earlier labeled version).
