I managed to simplify the script down to a one-liner - giving the same version as Edourard's: (display (run-with-store (open-connection) (package-file icedtea-8 #:output "jdk"))) Bjoern was correct that this was not the version I was looking for - but having rethought my dependency issue - I managed to solve it a different way using substitute* to patch the relevent files at build-time. Still, I learnt quite a bit about the gexps, the store, and patching - so time well spent - thanks again :-)
