trunk is in a buildable state actually at least for compiling the wxwidgets interface, I'm working on a few things, but try compiling it. The original contributor posted some notes http://darkalpha.homelinux.org/wxvbam/#binaries about compiling wxvba-m on osx (and all required dependencies) so it maybe worth looking into. mind you the wxwidgets interface code is still in development and should be considered alpha quality so only attempt if you are brave, if not build the gtk interface using the pre-wx repository
