Thanks Robby, that definitely helped (although I’m not finished getting this to work). Checking the correct sequence: 0. cd ~/src 1. git clone https://github.com/racket/racket.git 2. cd racket && make PREFIX=/usr/local 3. cd .. && /usr/local/bin/raco pkg update —clone math (this worked FWIW and cloned the math collection to my ~/src directory) 4. cd racket && make PREFIX=/usr/local (to install the updated math package into this copy of racket) 5. /usr/local/bin/racket (to test changes in REPL) In my case, I think part of my problem was a) two copies of Racket installed (so I needed to be more specific about which raco to use) and b) not understanding where raco is doing its work.
