I'm playing around with VMMaker.

Any attempt to build the resultant source code on a FreeBSD system 
results in the error:

   Variable PLUGINS_O is recursive

Line 453 of the resultant Makefile has the following:

   PLUGINS_O:=$(PLUGINS_O) {and then all of the plugins are listed}

I remove the $(PLUGINS_O) from the line, and all seems to work.
