How do I get etherape to work in OS X 10.6.6?

[Zack Perry]

I made a small progress.  I decided to download the latest stable etherape-0.9.10 source and build it myself, using libraries that were built when I was trying out the macports version.
Once I sudo myself into root, I performed the following.  Now I can see IP addresses, but still not node cicles and traffic graphs.  
I am contemplating to rebuild all libraries that etherape depends; using all latest stable to see if it make any difference, but I know given my current work load, such a time consuming task may have to wait.  So, I would appreciate any hints.
Thanks,
