Python cannot find find the module, so you might have to adapt you PYTHONPATH 
to include the folder where air_modes is installed (something like 
/usr/local/lib/python2.7/site-packages). Then you will most likely run into 
problems with shared libraries that can be fixed like this

If you run it and it segfaults assert (with cmake) that you use the python 
libraries from port which are typically installed under /opt/local. By default 
it selects the libs from OS X.

Best,
