I've tested your code on Mac Os X, it works fine :)

1. Compile and install OpenCV (http://bit.ly/1j2pjL)

2. Config your mex compiler if you haven't done it already (mex -config)

3. Compile Sreekar's code with Matlab as easily as:
mex FaceDetect.cpp -I/usr/local/include/opencv -L/usr/local/lib -lcxcore -lcv -lcvaux -lhighgui -lml

Hope it helps to the Mac beginners ;)

And, thanks Sreekar for your code!!!
