[boost] Boost 1.9 on Mint 20.1

I install Boost 1.9 on my Mint 20.1 system. I folowed al the steps shown on the Boost web page. It appeared to install without errors. I also enter the three environment varibles per the instructions. Now when I try to install a program that needs Boost >1.83 it defaults to Boost 1.7. Why does the program (wsjt-x Ver 3.0) not see Boost 1.9? What can I do to make Boost 1.9 avalable to fill this dependecy? Thanks Marty McGlensey843-546-4822mmcglensey@yahoo.com
