I've gotten this far trying to install this on Lion:
brew install gfortran
sudo easy_install scipy
sudo port install opencv +python27
export PYTHONPATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/:$PYTHONPATH
wget http://openmdao.org/releases/0.5.0/go-openmdao.py
sudo python ./go-openmdao.py
cd ~/Downloads/webcam-pulse-detector-master/openmdao-0.5.0
. bin/activate
cd ~/Downloads/webcam-pulse-detector-master && python get_pulse.py
Hope it's helpful to anyone else doing the same. OpenCV is segfaulting now, but I may update this later if I get it.
As some already noted, there are other animals like this: http://en.wikipedia.org/wiki/Negligible_senescence
