Yes, I'll try to update argparse to the version in 2.7 official, as it
will move us in the direction of less bundled utilities.

...

All of this seems to indicate that you are somehow mixing an old,
0.10.x tree with the tests for the current code.  In 0.11.x we
reorganized the big code dump from the original ipython into a more
rational structure, but your tests can't seem to find *any* imports.
That seems to indicate that you are finding on your PYTHONPATH the old
code first.

Try this and let us know what you get (from a plain python shell):

>>> import IPython
>>> print IPython.__version__
0.11.alpha1.git
>>> print IPython.__file__
/home/fperez/usr/lib/python2.6/site-packages/IPython/__init__.pyc


Also, looking at which one of these imports work will be a good
tell-tale sign (from a normal python shell).  If you have the real
0.11 tree, you should get:

>>> import IPython.core.ultratb
>>> import IPython.ultraTB
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named ultraTB


whereas a 0.10.x tree gives the opposite:

>>> import IPython.ultraTB
>>> import IPython.core.ultratb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named core.ultratb


Cheers,
