I was able (after a bit of a struggle) to install networkit via pip install networkit in a python3.6 anaconda environment (I'm on Mac OSX high sierra). In order for networkit to work I had to install a g++ compiler which supports OpenMp, so I chose to brew install gcc. Installation went fine but when importing the module I get the error

which I think depends on the fact that I am not using the Homebrew gcc but the default Apple Clang which does not support OpenMP. My question is: how can I set g++-7 to be the default compiler so that I get my networkit module up and running?
