Installation fails with node v0.12.0

Start with src/cpu_profiler.h and src/cpu_profiler.cc, then inspect src/profile.h and the node-gyp build configuration. Reproduce the failure with npm install under Node v0.12.0 and compare the native addon interfaces used there with the reported V8 errors. Done means the package installs successfully on that Node version.
