Although this is copied from the other descriptions of *ddir*, it and the other instances (and the description of the -d option) should all really be fixed. As I discovered when writing the tests for the -d option, what ddir is is the path that is "baked in" to the .pyc file. In very old versions of Python that meant it was the path that would show up in tracebacks as the path to the source file. In modern Pythons the ddir path shows up if and only if the .py file does not exist and the .pyc file is being run directly. In 3.2, this means it will never show up normally, since you can't even run the .pyc file without moving it out of __pycache__. Which means 'ddir' is henceforth useful only to those people who want to package sourceless distributions of the python code. (If you want to see this in action check out the -d tests in test_compileall.)
So, 'in error messages' really means 'in tracebacks if the .py file doesn't exist'.
