Recommended install via PyBombs fails on macOS High Sierra

[devnulling]

Moving this issue to here from: gnuradio/gnuradio#1531

System versions

System version: macOS 10.13.1
Package manager: Homebrew (due to an OOT module needing PythonNet, macports can't be used)
Python version: Python 2.7.14

How to recreate

After creating an installation prefix (step 4 of the quick-start):

$ pybombs install gnuradio

Output

PyBOMBS - INFO - PyBOMBS Version 2.3.2

@nsbruce tagging the OP (or trying to ...)

I would be -very- surprised if PyBOMBS actually works on OSX, given that there are no internal references to DYLD_LIBRARY_* ... there are to the Unix-y LD_LIBRARY_*, which leads me to believe that there is library path manipulation & hence why on OSX I doubt it will work.

Is pythonnet this: https://pythonnet.github.io ...? If so, I'll see if I can add it to MacPorts.

The tag worked @michaelld. I see what you mean about the references. It's been a while since I tried to do this. I'm not sure if it's still a relevant issue since that's two macOS versions old. I think I switched to a dockerized-GR when this didn't work.

Whether for this issue or not, having pythonnet available on MacPorts would be useful!
