It works for some modules, but not for the one I'm actually looking for -- perhaps it's relevant that murphy/protobuf is a planet module, included as (planet murphy/protobuf)? My understanding was that those will still be cached locally. Here's my output: [dstorrs@MacBook-Pro:~/cancer/app:<dks*>]$ racket racket Welcome to Racket v6.6. -> (collection-file-path "list-utils.rkt" "dstorrs") (collection-file-path "list-utils.rkt" "dstorrs") #<path:/Users/dstorrs/Dropbox/dstorrs/personal/study/scheme/dstorrs/list-utils.rkt> -> (collection-file-path "main.rkt" "protobuf") (collection-file-path "main.rkt" "protobuf") ; collection-file-path: collection not found ; collection: "protobuf" ; in collection directories: ; /Users/dstorrs/Dropbox/dstorrs/personal/study/scheme ; /Users/dstorrs/Dropbox/dstorrs/personal/study/scheme ; /Users/dstorrs/Library/Racket/6.6/collects ; /Applications/Racket_v6.6/collects ; ...
