The opengazer project is quite old. It seems to have its last release about two years. I'm guessing a lot has changed in those years, and so I'm getting many undefined references  in trying to compile it against the current vxl (compiled from svn). It seems like most of the references are to destructors. I'm hoping that this is the result of a design shift that happened at some point in the past two years and somebody suggested a fix for it or knows a good way around it or a consistent method for updating code from before that change point. I don't mind changing the code, but I didn't see any explicit calls to the destructors or to the delete function.
