I have no idea what I'm doing.

Out of the box on node 0.10.3, npm 1.2.17, mac os x 10.8.3:

    CXX(target) Release/obj.target/node-libvirt/src/node_libvirt.o
    ../src/node_libvirt.cc:2:9: warning: 'BUILDING_NODE_EXTENSION' macro redefined
    #define BUILDING_NODE_EXTENSION
            ^
    <command line>:4:9: note: previous definition is here
    #define BUILDING_NODE_EXTENSION 1
            ^
    1 warning generated.

followed by:

	module.js:356
	  Module._extensions[extension](this, filename);
	                               ^
	Error: Symbol node_libvirt_module not found.

right. This seems to fix it, probably something to do with node module api changing?
