gnuradio 3.8 on macos

[Kai Garrels]

Hi,

I am trying to move to gnuradio 3.8 using macports, but I fail:
        - gnuradio installs 3.7.something
        - gnuradio-devel dos not install
        - gnuradio-next installs 3.9, which conflicts when apps look for 3.8 

What I want to achieve: gnuradio3.8 + gr-osmosdr….any suggestions?
Should I use something else than macports?

Thanks for your help!
