edlib: edlib installation fails in conda python if gcc not installed

I’m not posting an issue per say, but more of a config problem if others run into it they can find this. But I’m on Mac, running miniconda2, if you try to install edlib without first installing gcc via condo you get a compilation error. conda install gcc fixes this.

pip install edlib --no-cache-dir
