I am the author of this code. If you're interested in getting started with it right away then check out Eucalyptus: https://github.com/yahoo/rtrace/tree/master/Eucalyptus

I wrote Eucalyptus as the primary unit test for rtrace but its a fully functional native code debugger. Here is an example of how you can configure it using Ruby to trace calls to malloc() and print out some information:

If you're interested in contributing, the signal handler in Rtrace could use some cleanup. Helper methods for interacting with procfs and the process memory are always useful too.
