+you'll need to get a file called
+haarcascade_frontalface_alt.xml
+i was able to get it with this:
+ wget http://eclecti.cc/files/2008/03/haarcascade_frontalface_alt.xml

+
+if you're on ubuntu:
+make ubuntu-dependencies
+make
+make test # assumes you have haarcascade_frontalface_alt.xml in current dir
