Attached is as far as I got over the weekend. As you can see the main problems (apart from the lack of hyper which is a showstopper) are: * Minor header tweaks * PKG_CHECK_EXISTS macro doesn't exist and has to be commented out everywhere. This is despite the fact that I have pkg-config from Macports installed. * --version-script not supported by the linker It's actually very close to working, and I think it will be considerably simpler to port and maintain a Mac OS X port than the wretched Windows port. The OCaml bindings & tools built first time on Mac OS X, but obviously I couldn't finish the final link since there wasn't a libvirt.dylib.
