line 295, in ant_iter
    raise StopIteration
StopIteration

The above exception was the direct cause of the following exception:

RuntimeError: generator raised StopIteration
[mamu at verstappen rtems-tools]$ ./waf-2.0.12
The project was not configured: run "waf configure" first!
[mamu at verstappen rtems-tools]$

python is symlinked to python3 and ./waf crashes and the fresh
waf-2.0.12 executes fine.
