Comment:

 Hello, thanks a lot for your comments,

 I did the following installations before trying to install gnu radio:

 1-Jonathan Naylor's MMDVM from GIThub (https://github.com/g4klx/MMDVMHost)

 2-Rogerclarkmelbourne Arduino_STM32 issue #256 from Github
 (https://github.com/rogerclarkmelbourne/Arduino_STM32/issues/256)
 Issue: macOS: libusb is not included, that dfu-util depends on #256
 following recommendations from the community i executed the following:
 brew install libusb
 sudo mkdir -p /opt/local/lib
 sudo ln -s /usr/local/Cellar/libusb/1.0.21/lib/libusb-1.0.0.dylib
 /opt/local/lib/libusb-1.0.0.dylib

 3.GQRX binary package GQRX-2.11.5.dmg.

 I believe option # 2 is the cause of my problem with the Gnuradio
 installation, that patch solved my  problem with the arduino_STM32
 package and I would not want to loose this fix, is there a procedure to be
 able to complete the Gnuradio installation without loosing this fix?

 Thanks very much again and best regards,

 Abraham
