Trouble compiling (newby)

[tbrooke]

I used: raco exe racket-format.rkt - with no options and got the error below

format.rkt:5:9: collection not found for module path: memoize collection: "memoize" in collection directories: /Users/tmb/Library/Racket/6.5/collects /Applications/Racket v6.5/collects

Right, memoize is a library that unfortunately doesn't ship with Racket by default. I need to try to figure out an automated solution to that, but in the meantime it can be manually installed as a workaround:

raco pkg install memoize
