$ brew update
$ brew upgrade # may be unnecessary
$ brew tap metacollin/gnuradio
$ brew install gnuradio # took 55 mins on my laptop & installed python via homebrew
$ brew install librtlsdr --HEAD # this installed b4c4e723f3656954f160b3f8df4e8804e4a46acd for me
$ brew tap chleggett/gqrx
$ brew tap chleggett/gr-osmosdr

$ brew linkapps gqrx
$ open /Applications/Gqrx.app/Contents/MacOS/Gqrx

I was running into compile issues with gnuradio on El Capitan 10.11.2 with cmake 3.4.1. [get_filename_component called with incorrect number of arguments]

Downgrading cmake to 3.3.2 allowed gnuradio to compile [https://github.com/Homebrew/legacy-homebrew/issues/46000]:

brew install cmake; brew unlink cmake
cd /usr/local/Library
git checkout -b cmake 0036e3d1
brew install cmake; brew switch cmake 3.3.2
git checkout master
brew install gnuradio

Also there is no need to use brew tap metacollin/gnuradio anymore, as it's now in the homebrew repo. [noted via https://github.com/chleggett/homebrew-gqrx]
