What I have done is supply a patch and a script to copy the code from your NDK installation, patch it up to use profiling, update the build scripts and then build the example. You'll need to have the "patch" program installed to get this working, or apply the changes manually.
Since this is Android 2.3 only, I've only been able to test it on the emulator. Also the emulator doesn't like armeabi-v7a, so that remains completely untested - I'd stick to using
APP_ABI := armeabifor profiling for now.
Hopefully this'll clear up any misunderstandings like those mentioned in the comments on the last post I made on the subject. Full details are on this wiki page about getting the example working.
