I would not do it quite that way. Here's the steps I recommend: git clone https://github.com/racket/racket.git cd racket make # get some coffee here mkdir extra-pkgs cd extra-pkgs # make sure `raco` in your path is the one you built just above raco pkg update --clone math
.... now do git stuff / racket stuff. The upside to avoiding the "PREFIX=..." is that the racket installation is now completely contained in that directory. Just throw it away when you're done with it and if you have more than one (perhaps you want to try out an older version or a released version or something) all you have to do is update your path. And if you want to update to get some bug fix or improvement, simply do a git pull and make in the top-level directory again. (That "make" really does include all of the steps, like it'll run configure and do all kinds of things so you don't have to worry about it.) And the "extra-pkgs" directory is just the convention some of us use.
