Looks like you built the master branch of GNU Radio, which defaults to Python 3. To resolve those failing tests, you need python3-scipy and python3-zmq.

Any suggestion please. I tried to see some of the previous thread and suggested to install python-scipy which I did and sounds I have newest version. Please see below:
python-scipy is already the newest version (0.17.0-1).

    Hi Rajesh - CMake found your GR38 install, not your GR37 install.
    You should pick GR37 or GR38 and go with just it, and remove the
    one you're not going with. Then, pick the same branch of
    gr-ieee802-11. Hope this is useful! - MLD

        Hi Ron,

        Sounds good, seems a bit progress.
        I think other than Cmake policy, attached in screenshot I am
        almost there. Do you think I would need any other requirements?

            Okay, here's the complete set of instructions.

            git clone https://github.com/bastibl/gr-ieee802-11.git

            cd gr-ieee802-11/

            git checkout maint-3.7

            mkdir build

            cd build

            cmake ../

            make

            sudo make install

            sudo ldconfig

            Make sure you use the correct install prefix in the cmake
            step. You can determine the install prefix with:

            gnuradio-config-info --prefix

            cmake ../ will install into the default prefix, which is
            usr/local. If you have any other prefix, you need to
            specify that with the cmake command. For example:

            cmake -DCMAKE_INSTALL_PREFIX=/usr ../
