I think that you can safely ignore these messages. External plugins
can have a function called shutdownModule(), which is executed when
the plugin is unloaded (this occurs when Squeak exits). If the function
does not exist, you will get a warning message. My guess is that you
had VMMaker build a lot of plugins externally, and maybe some of them
do not have a shutdownModule() function.
