GNURadio, AirProbe, libosmocore for OS X 10.8 Mountain Lion

First you need to install Homebrew

Then you need to install GCC from XCode "command line tools"

$ brew install gfortran umfpack swig
$ sudo pip install  numpy Cheetah lxml scipy matplotlib
$ brew tap ksnieck/homebrew-gnuradio
$ cd /usr/local/Library/Taps/
$ mv ksnieck-gnuradio/ titanous/homebrew-gnuradio
$ brew install gnuradio
$ brew install rtlsdr gr-osmosdr gr-baz --HEAD

There's like a shitton of dependency for GNURadio, you'll possibly need a fast Internet connection or wait.
