This[1] ditaa example with ORg 8.2.7f under Mac OS X Mavericks fails with a message indicating that .../elpa/contrib/scripts/ditaa.jar is not found. I created the folder and soft-linked /usr/local/bin/ditaa to ditaa.jar and tried again. This time the export ran, but the PDF it created contained a large box with ":file somefile_name.png" inside it. I've also read this[2] and did not find ditaa in ELPA. Suggestions?
