Hi Martin,

It sounds like you may be using an outdated version of VMMaker. All
of the literal references to "4" were removed from the file and socket
plugins a long time ago.

The VMMaker on SqueakMap is version 3.8b6. In your development image,
if you evaluate "VMMaker versionString" should see something similar.

p.s. OSProcessPlugin, XDisplayControlPlugin, and AIOPlugin are also
updated for 64 bit, so you can include them in the build if you like.
