PSA: Use Boost version between 1.61 and 1.68, ROS breaks when updating brew now

[connorsoohoo]

Boost version 1.69 removes the signals package, so a lot of the roscpp packages won't compile. brew only has 1.70 available, so when you update brew it will break the ROS install. To workaround this, I used MacPorts instead (sudo port install boost) to get 1.66 instead and then explicitly specified my -BOOST_ROOT=/opt/local/ in the additional CMAKE args when calling catkin config

Can you please help me out with installation of Boost 1.66 and switch from boost 1.70.
sudo port install boost not working in my case and also boost and boost-python both are 1.70. How to change all dependencies boost to 1.66. I searched a lot but could not find the way.

Thanks

I solved the port issue by installing it again https://www.ghostwheel.com/2018/09/22/installing-macports-on-macos-10-14-mojave/. Now I am able to install boost 1.66 using port https://trac.macports.org/wiki/howto/InstallingOlderPort and also edited install file with adding -BOOST_ROOT=/opt/local/ in CMAKE args when calling catkin config

but now it is throwing error:
