Does anyone have any experience with installing dynr?
I am using a Mac with the Catalina software. I have installed Xcodes and MacPorts as per the recommendation in the User's Instruction Manual (attached), but have no experience with either of these. Instruction 2.1.3 says to type "sudo port install gsl" into the terminal window, but when I do this I get error terms which leads me to believe I'm not typing it into the correct place (picture attached).
Any advice would be much appreciated!
