Looks like I was wrong :-) The custom shadowing seems to play a role.
Just guessing, it's probably a chicken-and-egg situation: you load the
custom file before org gets initialized and there is no autoload that
manages to get the macro defined before it is used.

One way to break the loop is to not use the macro in your custom file:
replace it by its definition. Another way is to delete the customization
of org-ditaa-jar-path from the custom file and include it after org gets
initialized. Both of these are to be considered workaround hacks than
solutions, but it's hard to propose a solution without knowing exactly
what the problem is.

If you still can't make it work, please post the initialization file(s)
and the two custom files and maybe somebody can figure out something.

HTH,
Nick
