An issue I've repeatedly encountered when trying to use Babel with ditaa is that ditaa.jar never seems to be available despite a few claims in the documentation that it is distributed with Org. Since I'm already trying to find the source of my octave issues from my previous post, I thought I may have installed Org improperly and decided to wipe out my .emacs.d and start over.
I see that now Org has its own elpa repository (so far, so good), so I added it as my second (well, first in customize) package-archives entry after removing my .emacs.d directory to run my 24.3.1 build from my home directory (with .emacs modified only using Custom, and only containing standard org- and package- settings). I refreshed the package list, and installed the "org-plus-contrib". Everything seemed successful (Total of 161 files compiled, 1 failed, 4 skipped); I got some errors in the install output buffer, but nothing mentioning ditaa explicitly except "Compiling ... ob-ditaa.el". So now when I exit Emacs I expect the following command to produce output: find ~/.emacs.d/ -name ditaa.jar but it still does not. Lowering my expectations slightly, I hope for output from the following: find ~/.emacs.d/ -name contrib but still nothing. I assume I am installing Org improperly somehow, despite the fact that my version shows correctly: Org-mode version 8.2.5h (8.2.5h-32-g9639ed-elpaplus @ /home/pregier/.emacs.d/elpa/org-plus-contrib-20140310/) Am I missing something obvious?
