edit

I successfully installed OpenCV on Mac OS X 10.8.2.

After that I configured Xcode 4.5.2 by following this guide by SSteve even that this guide was for Xcode 3.5.1 - everything was are it's suppose to be.

My openCV dylib's are in: /usr/lib

1. Always Search User Paths: YES
2. Framework Search Path: /usr/lib* (* stands for recursive search)
3. Header Search Path: /usr/lib* (* stands for recursive search)

Full error message:
