I'm not sure this is the best way (or even the correct way!) to do this. As I recall, I was having a problem, because *file* was only available while compiling and was nil at runtime. I ended up using these macros with defvar from clojure-contrib to find my path and bind it once during loading, like so: (defvar *downloads* (join (__DIR__) "cache" "downloads") "The root path for the download cache") Not sure if all of those assumptions are still valid, but if it helps someone, then there it is.
